If we change the duration of a pure tone of 1k Hz from 500ms to 1 second, it will sound____

Basilar membrane tonotopic mapping means: each location on the basilar membrane responds to a limited range of ____

In signals shorter than 200 ms, as duration_____, absolute threshold ____.

According to the results from Small, Brandt and Cox (1962), which of the following statements is true about audibility and duration?

According to rate-place code in pitch perception of pure tones, a neuron fires fastest when the frequency of the sound is equal to the characteristic frequency of the neuron.

If someone has wider auditory filters, their frequency resolution is ____, and they tend to have ____ difficulty with hearing speech in noise.

A bandpass filter ____ pure tones have frequency close to the center frequency of the filter, and ___ pure tones have frequency further away from the center frequency of the filter

If your absolute threshold for a 200-ms 1kHz tone is 5 dB SPL, you cannot detect a 100-ms 1kHz tone played at 5dB SPL.

Pitch of complex tones is perceived by the mechanisms of phase locking to the wave of lower harmonics and to the envelope of higher harmonics

One of the reasons for those who are older and/or have hearing loss to have more difficulty with speech understanding in background noise

In signals longer than 300 ms, what is the relationship between duration and absolute threshold?

Frequency difference limen is the lowest and pitch discrimination is the best for sounds ___

Can the amplitude affect the volume?

What pitch perception mechanism is working for pure tones that are higher than 4kHz?

What is the perception variable that is corresponding to the stimulus variable of frequency?

Can the pitch affect the frequency?

Can the amount of amplitude and frequency affect the energy?

Because the laws of electrostatic, magnetism and gravity are so closely related, many prominent physicists have worked to try and
