Introduction
to the VocaLog 2™ Vocal Activity Monitor
The
VocaLog
2™ Vocal Activity Monitor provides a system for objectively evaluating
and treating
Sound Pressure Level (SPL, measured in dBC)
in voice
patients. The
VocaLog 2™ system consists
of the VocaLog 2™ Activity Monitor worn by the patient to monitor and
record vocal
activity, the PC software, and a Calibration Microphone. Using the VocaLog2 Desktop
Application on
your PC, the clinician can download the data recorded by the Monitor. Together, they provide a
means to monitor
your patients’ vocal activity for direct interpretation by the
clinician and
feedback to the patient on established treatment goals.
The
VocaLog2 Desktop Application software allows you to interpret the data
collected by the VocaLog Vocal Activity Monitor.
Using the VocaLog 2™ System, you can
initialize and calibrate the Vocal Activity Monitor, connect remotely
to
monitor and receive data for analysis within the VocaLog Desktop
Application
Software, and monitor daily patterns in your patient’s vocal activity
to
determine when the patient’s volume is outside the range of established
loudness levels.
Notice:
The VocaLog 2™ system does not record voice, sounds, or speech. It does
not
recognize speech. It only logs Sound Pressure Levels using the dBC scale.
Getting
Started:
Installing
the
VocaLog 2™ System
The
VocaLog
2™ Desktop
Application must be installed on a Windows® PC prior to
operating the VocaLog 2™.

VocaLog
2™ Hardware Overview
The VocaLog 2™ Vocal
Activity
Monitor
hardware consists of a neckband
“monitor” and a USB microphone used during calibration. The following
section
will outline the various features of the hardware.
MONITOR
In-Ear
Auditory Alerts:
OPTIONAL
FEATURE: Not
included on all units. To use, insert the ear piece over the prong
located on
the VocaLog2 neck band. When auditory
alert mode is enabled, the
VocaLog 2™ Unit will emit an audible signal any time undesired vocal
activity
is detected. To
adjust volume simply
press the V+ button to increase
volume, and the V- button to
decrease volume.
Vibrotactile
Alerts:
The
VocaLog 2™ Unit has the
ability to vibrate when undesired vocal activity is detected (either
too soft
or too loud). Slide
the switch labeled VIBE on the neck
band to the vibe
position to enable the vibratory mode.
This
feature can be disabled during the calibration routine.
R
Standby
Mode:
Slide
the switch to the SLEEP mode when
the VocaLog 2™ unit is
not in use to preserve battery life.
This
is also recommended when the patient is not wearing the monitor, to
avoid
picking up noise.
The
VocaLog 2™ Laryngeal
Sensor
The
Laryngeal Sensor on the
VocaLog neck band unit detects the patients’ vocal activity and
transmits the
data to be stored. Proper and consistent placement is essential for
accurate
calibration and monitoring. The sensor should be located just above the
sternal
notch, and must be flush against the skin with enough pressure to
ensure
constant contact. To assess proper fit, direct the patient to move
their head
side to side and up and down several times.
The sensor may self-align with initial movements, and
should not move
once properly positioned.
Size
Selection:
Sizes
are based on neck
size, in centimeters. Use the included flexible ruler, and not shirt
size. In
general, most women will use a size 28, and most men will use a size
35.
Size
28, for neck sizes 28
to 35cm
Size
35, for neck sizes 35
to 42.5cm
Size
43, for neck sizes
42.5 to 50cm
The
unit must be adjusted prior to
calibration, and must be recalibrated after adjustment.
Length: There
is about 2cm (.8") of adjustment in
each size. The correct size must be ordered. The neck band may be slid
into or
pulled out of the main housing to lengthen or shorten the neckband. Do
not
force it. Adjust for comfort; the main housing should wrap around the
neck more
than 180 degrees so it does not shake off easily.
Curve:
The
VocaLog 2™ Laryngeal Sensor has a durable wire frame which can
be bent and adjusted for proper fit. It
is recommended that slight adjustments be made,
and test for fit between each adjustment.
To
tighten:
Cross the two ends over each other until the desired fit is
achieved.
To
loosen:
gently pull the two ends away from each other until desired fit
is achieved.
WARNING:
A loose fit may cause loss of accuracy, due to inadequate pressure on
the
sensor.
The
VocaLog 2™ Unit
includes a built-in rechargeable battery. A green blinking light near
the USB
port of the VocaLog unit will briefly flash every two seconds when the
battery
power is low, and not plugged in for charging.
Charging
the
The
VocaLog 2™ unit should
be charged prior to first use. We also recommend charging it every
night.
The
VocaLog 2™ unit is
charged through the built-in Micro-USB port through any USB connection
(e.g. a computer,
car adapter, or home charger). An
LED
light will illuminate while the unit is charging and will slowly blink
(once
per second) when charging is complete.
A
fully charged battery will run continuously for up to 3 days depending
on use. Alerts
increase battery drain. Charging
an
empty battery may take up to four hours.
MICROPHONE
The
VocaLog 2™ Calibration
Microphone
The
VocaLog 2™ Vocal
Activity Monitor includes a specially calibrated USB microphone for use
while
calibrating the monitor to the patient.
Please ensure that you have plugged in the microphone and
your computer
settings are enabled for microphone activity. The
first time you run the PC program, you
will be prompted to enter the calibration key located on the front of
the calibration
mic.
Do not
discard this number.
VocaLog
2™ Desktop Application Instructions
The
VocaLog
2™ desktop application is used to manage
patients, calibrate a monitor, update settings, and review collected
data. In
the section below, you will learn how to utilize the main features of
the
program.
Each
time you open the
program you will be presented with the main menu shown below. This is
the
starting point for navigating through the program.
To return to this menu, simply click the Main
Menu button in the top right corner of the screen.
Use
the Main Menu tabs to navigate the
VocaLog 2™
Desktop Application. Note:
When a
monitor is not detected, only the
option Manage
Patients will appear.
Menu options include:
1.
Add New Patient
2.
Manage Patients
3.
Receive Data
When
selecting “Add New
Patient”, a privacy alert will appear.
This is just to allow you to keep the patient data
private. Click
[Continue]. You
will then be prompted to
enter the patient’s name.
NOTE:
If you have multiple
patients with the same name, i.e. John Smith, you must give each
patient a unique
name or only one record will be created.
From
there, you will be
taken to the Monitor Set-up sub-tab on the Connect to Monitor tab. Three steps are
then clearly displayed:
Step
1-
initializes the monitor - The monitor must be initialized in
order to clear the VocaLog
memory
and prepare the
device for calibration.
Step
2
-allows you to enter any relevant notes about the patient
Step
3
- starts the calibration wizard - This will set up the monitor
for use by the new patient.
Note:
Your time and date must be current in
order to ensure accurate data collection.
The
first screen you will
see after clicking [Calibrate Now] is on the Connect to Monitor tab. This tab allows you to
manually select
individual tasks to do with a monitor. At the top of the screen is a drop-down selection
to select which
monitor you will be working with. If you only have one monitor, it
defaults to
that monitor. If you have more than one plugged in, be sure the
appropriate
monitor is selected. The Calibration
Wizard automatically directs you to the
Preparation:
The
Calibration Microphone should be
placed 30cm (11.8") from the
patient. Maintaining a consistent distance will improve accuracy.
Ensuring the
patient is comfortable will help.
On
the VocaLog 2™ Vocal
Activity Monitor, verify the SLEEP switch is turned off (slid away from
SLEEP).
Set the VIBE switch towards VIBE if you want the patient to receive
vibrotactile feedback.
Prior
to launching calibration, ensure you are
in a quiet room with minimal
background noise as this will interfere with the calibration. You
will receive a warning message if the ambient noise is too high.
Process:
Select
the type of patient
you will be working with.
The
button [Change Patient Alert
Settings] skips the calibration process and allows you to jump to the
Calibration Completed step and make adjustments to the patient's alert
levels
without recalibrating the device. This should not be selected for new
patients.
Follow
the on-screen
prompts and instruct your patient to perform each task as it is
displayed. If
you are not satisfied with a task, click Go Back and repeat the task. When possible, tasks
should be started
immediately upon pressing the Start button.
After
the tasks are
completed, select the type of alert you would like your patient to
receive.
Choose
whether you would
like to utilize the Ambient
Noise Compensation.
If you choose to use it, enter the dB appropriate for the patient.
Once
Calibration Wizard
is
complete, optimal settings for the patient will be provided based on
data
collected. You can
modify the alert
settings and fine-tune the VocaLog2 monitor for the patient using the
arrows
next to each setting. For best results, it is recommended to have the
patient
speak at their targeted volume. You will see a real-time visual display
of
their vocal levels at the bottom of the screen.
-For
Hypophonia patients, red
indicates the volume was too low which would result in an alert
to the patient, green
indicates the patient is speaking at or above their targeted
volume.
-For
Hyperphonia patients, Blue
indicates the volume was in the target range (i.e.
"Normal" speech"), and red
indicates the patient is speaking at or above their targeted
volume, which would result in an alert to the patient.
Patient
Alert Setting Descriptions:
Standard
Options:
Minimum
Phonation Volume:
This is the quietest volume that will be detected
as voice or phonation. Any detected sounds quieter than this level will
be
discarded, and not considered phonation.
Targeted
Phonation Volume:
With Hypophonia patients, this is lowest acceptable level
at which they should speak.
With Hyperphonia patients, this is the highest acceptable
level at which they should speak.
Alert
Delay:
This is how long the device waits at a continuously undesired
level before alerting the individual. This is patient specific;
suggested
values are .75-1.00 second(s). Smaller values alert the individual
faster. A
very sensitive individual on voice rest may require a very fast (.25
sec)
alert. Individuals who only speak in brief phonation may also require a
shorter
delay. Too short of a delay will result in excessive alerts, and may
result in a
user ignoring alerts.
Alert
Type: Modify:
This button allows you to go back and modify
the Alert Type settings.
Ambient
Noise Compensation: This may
be turned on or off. This allows the alert levels to vary, depending on
the
ambient noise. The Ambient Noise
Compensation does not adjust the target levels; only the
alert levels. For
instance, a Hypophonia patient may
require a higher alert level in a louder room. This is because a louder
environment
will require an individual to speak louder in order to be heard over
ambient
sounds. However, activating this feature and adjusting this value does
not
change the Targeted Phonation Volume,
so the patient may receive an Alert while within their target.
Note:
Discretion must be used for voice-rest individuals; this feature
may not be beneficial.
Ambient
Noise Compensation dB: This is
the number of dB added to the ambient sound level for alerts. Suggested setting: 0 or 1.
Higher values will
result in an Alert unless the patient is very loud.
Maximum
Phonation Volume: The
ambient noise compensation will not exceed this.
Microphone:
This
is a real-time display
of the microphone dB readings. The green
(or blue)
flag indicates a graphical position of Minimum
Phonation Volume, and the red
flag indicates the Targeted
Phonation Volume. The yellow flag moves with the patient
Sound Pressure
Level (SPL,
in dBC).
Typical
Numbers For Reference:
Minimum Phonation
Volume is typically 50-60dB, and varies between individuals.
Normal Conversation at 1 meter in a quiet room is 60-65dB.
Targeted Phonation
Volume must
be selected by a
clinician, based on the individuals' needs.
Verify
and Fine-Tune Values:
Have
the patient speak
(i.e. read the Rainbow Passage), and observe the Microphone values.
While they
are talking, the meter should nearly always be above the Minimum
Phonation Volume.
The clinician must make the judgment call for appropriate
settings for
each patient. For instance, if a hypophonia individual struggles to
achieve the
target, you may need to reduce the target. Once
you have adjusted the settings to your
satisfaction, click [Save Calibration].
Select
Manage Patients to
be
brought to the
corresponding tab. This function enables you to view your
patient list, rename a patient, delete a patient, view any previously
collected
data-sets, view and modify patient notes, and modify existing settings.
There
are also shortcut buttons to [ Adjust Monitor Settings ] and [
Calibrate
Monitor ]
To
view a patient data
file, select the patient you wish to view and double-click the data set
thumbnail to open the patient’s file.
3.
Receive Data
To
download patient data
from the VocaLog2 Monitor, select Receive Data from the Main
Menu. Choose to Receive data and clear the memory,
or Receive
data only. It
is recommended
that you Receive
data only to ensure transfer is successful prior to
deleting the memory. After
data has been
received, the Analyze Vocal Activity page will display the patient
data.

How
do I enter BOLD text in my
reports?
All
text is plain text at
this time. You may copy and paste the text into a word processor if you
wish to
format the text.
Why
does my report contain
highlighted fields, when I know they are valid?
If
you have Placeholder
Fields for Selected Data in your report, but you do not have any data
selected,
it cannot fill in the data. Select some data in the graph, and the
report will
be completed.
Why
does the monitor vibrate
no matter what?
There
are two explanations
for this. The most common is when Ambient
Noise Compensation
is on, and the Compensation Value is too high. Only use 0 or 1,
unless you are experienced and are familiar with how this works.
If
that is not the case,
then it is advised to recheck the calibration values. Recalibration may
be
required.
What
is SPL?
SPL
= Sound Pressure Level.
In this document, it is measured in dBC.
Will
the VocaLog software work on my Mac?
No.
It requires a Windows
operating system.

When
the sunlight strikes
raindrops in the air, they act as a prism and form a rainbow. The
rainbow is a
division of white light into many beautiful colors. These take the
shape of a
long round arch, with its path high above, and its two ends apparently
beyond
the horizon.
There
is, according to
legend, a boiling pot of gold at one end. People look, but no one ever
finds
it. When a man looks for something beyond his reach, his friends say he
is
looking for the pot of gold at the end of the rainbow.
Throughout
the centuries
people have explained the rainbow in various ways. Some have accepted
it as a
miracle without physical explanation. To the Hebrews it was a token
that there
would be no more universal floods. The Greeks used to imagine that it
was a
sign from the gods to foretell war or heavy rain. The Norsemen
considered the
rainbow as a bridge over which the gods passed from earth to their home
in the
sky.
Others
have tried to
explain the phenomenon physically. Aristotle thought that the rainbow
was
caused by reflection of the sun's rays by the rain. Since then
physicists have
found that it is not reflection, but refraction by the raindrops which
causes
the rainbows.
Many
complicated ideas
about the rainbow have been formed. The difference in the rainbow
depends
considerably upon the size of the drops; the width of the colored band
increases as the size of the drops increases. The actual primary
rainbow
observed is said to be the effect of a super-imposition of a number of
bows. If
the red of the second bow falls upon the green of the first, the result
is to
give a bow with an abnormally wide yellow band, since red and green
light when
mixed form yellow. This is a very common type of bow, one showing
mainly red
and yellow, with little or no green or blue.
