Two-Channel Configuration Allowing Electrode
Placement Feedback
Glottal Enterprises Inc. Electroglottograph Features Feb 2015
• Allows user to know that they are using the optimum placement of the electrodes.
• You are assured that electrodes will be in the same place for consistency when comparing
data from one session to another.
• Saves the user time as they will know during the recording process if improper electrode
placement will result in a unacceptable recording.

Low Battery Indicator Light
Glottal Enterprises Inc. Electroglottograph Features Feb 2015
• There are two rechargeable batteries. Can easily switch to second battery when
the first one is out.
• Each battery should run for 12 hours.
• The EGG CANNOT run when plugged in. It was designed this way to avoid any noise
from the line power.
• The EGG is portable and can be taken into places where there is no power available.

Included Research-Quality Electret
Microphone
Glottal Enterprises Inc. Electroglottograph Features Feb 2015
• An omni-directional electret microphones is provides a high quality signal for critical
applications such as inverse filtering.

1/8” Microphone Jack Supporting Both Electret
and Dynamic Microphones
Glottal Enterprises Inc. Electroglottograph Features Feb 2015
• This Mic jack allows you to record a signal from the electrodes AND a microphone
simultaneously.
• Others do not have this option.

Laryngeal Position Tracking Signal Output
Glottal Enterprises Inc. Electroglottograph
Features Feb 2015
• It is a DC voltage that changes as your electrodes move up and down on
the neck.
• Seeing this signal along with your EGG signal confirms that the electrodes
were staying in the desired position while the data was being recorded.

Verified 40dB signal-to-noise Ratio for
Electroglottograph Signal
Glottal Enterprises Inc. Electroglottograph Features Feb 2015
• Individually tested for a guaranteed signal to noise ratio of at least 40db.
• This limits the amount of noise providing a better signal quality.

PhaseComp Software for Low-Frequency Phase Distortion
Compensation Included
Glottal Enterprises Inc. Electroglottograph Features Feb 2015
• Our PhaseComp software is included as part of the EGG Package.
• The high pass filtering that is needed to record the EGG signal introduces a waveform
distortion. This software attenuates or reduces this distortion.
• Makes the EGG signal a much more accurate representation of the vocal fold contact area.
• PhaseComp also reduces the “low frequency noise” generated by the many different
vibrations that are recorded along with the Vocal Fold vibration, (your skin and tongue for
example)
• No other EGG offers this feature
