ABSTRACT
Online auditory experiments use the sound delivery equipment of each participant, with no practical way to calibrate sound level or frequency response. Here, a method is proposed to control sensation level across frequencies: embedding stimuli in threshold-equalizing noise. In a cohort of 100 online participants, noise could equate detection thresholds from 125 Hz to 4000 Hz. Equalization was successful even for participants with atypical thresholds in quiet, due either to poor quality equipment or unreported hearing loss. Moreover, audibility in quiet was highly variable, as overall level was uncalibrated, but variability was much reduced with noise. Use cases are discussed.

'DEAR READER' MESSAGE

Dear Reader,

Included in the Box are the full dataset in csv format and sound examples (in the "Other' category).

Also included are Matlab scripts to help you generate TEN for your own experiment. TEN_generator is the main routine, try help TEN_generator for a first idea. TEN_use_examples has a few commented examples and an audio demo to get you started.

Any feedback welcome.

Enjoy!

Daniel
