Q:

Is this statement true or false: the greater the amplitude of a sound wave, the louder the sound?

A:

It is true that the greater the amplitude of a sound wave, the louder the sound. Amplitude is defined as the measure of change in atmospheric pressure caused by sound waves.

Amplitude is measured in the amount of force applied over an area and is most commonly measured in newtons per square meter (N/m2). A newton is considered the amount of force it takes to accelerate a 1-kilogram object by 1 meter per second (m/s).

The lowest threshold that a human can hear sound is 0.00002 N/m2. The threshold of pain for hearing a sound is considered to be 60 N/m2. Both of these numbers can vary depending on the individual and age but can be used as general guidelines.

For larger amplitudes, the amplitude does affect the period of the pendulum, with a larger amplitude leading to a larger period. However, for small amplitudes (typically around a few degrees), the amplitude has no effect on the period of a pendulum.

Diffraction occurs when a wave bends around objects. Diffraction is also said to occur when a wave spreads after it has passed through a type of gap.

The propagation constant is the rate at which the amplitude of a wave diminishes as it propagates outward from its source. The practical effect of this diminution is that wave amplitude drops at a predictable rate as the wave moves along a line of transmission.
