CONDITIONS:

1) Sound is presented 1 meter in front of the manikin through a loudspeaker speaker with Cessna 182 sound file. Sound pressure level is a constant 95dB SPL (a) at the ear.

2) Various headphones are substituted on the manikin and the resultant sound levels and audio spectrum are compared.

3) Air Traffic Control speech simulation is presented at a constant level of 75dB SPL through each headset tested. Audio spectrum is shaped to accomodate variability of frequency responses of various headsets.

The following sound files are the speech through the headset speaker + Noise transmitted through the headset.

The manikin has microphones in the ears that simulate the physicial properties of the average human ear.
