For sound waves in air with frequency 1000 hz a, Ask an Expert

Academics

For sound waves in air with frequency 1000 Hz, a displacement amplitude of 1.2 X 10^-8 produces a pressure amplitude of 3.0 X 10^-2 Use v_sound = 344.

A. For 1000-Hz waves in air, what displacement amplitude would be needed for the pressure amplitude to be at the pain threshold, which is 30 Pa?

B. For what wavelength will waves with a displacement amplitude of 1.2 x 10^-8 produce a pressure amplitude of 1.5 x 10^-3 ? C. For what frequency will waves with a displacement amplitude of 1.2 x 10^-8 produce a pressure amplitude of 1.5 x 10^-3 ?
