NeuroSounds



General

The auditory range: a sequence of tones of 50, 100, 200, 400, 800, 1600, 3200, 6400 and 12800 Hz.
A 200 Hz 'pure tone' (sinusoidal waveform)
A 200 Hz square-wave
White noise
A 135 microsec click
Frequency discrimination: alternating 400 and 404 Hz tones

Fourier synthesis of a 200 Hz square-wave

200 Hz fundamental
300 Hz, 3rd harmonic
500 Hz, 5th harmonic
700 Hz, 7th harmonic
Sequence: 1 + 3, then +5, then +7, then square-wave

Modulation and beats

Beats between a 400 and a 404 Hz tone
5000 Hz tone alternating with the same modulated at 200Hz
Noise alternating with the same modulated at 200 Hz
3100 Hz alternating with 3000 + 3200 Hz
'Missing fundamental': 200 Hz square wave with its fundamental subtracted

Binaural

'Short delay' means 45 microsec; 'medium' means 90; 'long' means 180.
In each sound-clip, the delay alternates between the ears.
400 Hz tone, short delay
400 Hz tone, medium delay
400 Hz tone, long delay
Noise, short delay
Noise, medium delay
Noise, long delay
Click, long delay
'Phaser': 400 Hz in one ear, 403 Hz in the other
'Phaser': 400 Hz in one ear, 401 Hz in the other
