Question

If pitch frequency amplitude are equal in human begins sounds what will happen

Answer 1

Frequency affects the pitch. I am not a specialist, but …

The higher the frequency, more energy the sound wave has.

High energy, high pitch sounds are irritating, propagate with ease and should be avoided wherever possible.

For chimes, aural alerts, and alarms low pitch sounds are preferable.

Amplitude is the volume (as stated by Keenan Hye), usually measured in decibels, dB.
