What describes how high or low a sound is?

• A. Pitch
• B. Circuit
• C. Reflects
• D. Absorb

Answer: (A)

Pitch describes how high or low a sound is. This depends on the frequency of the sound wave: higher frequency waves arrive more often per second, and our ears interpret that as a higher pitch; lower frequency waves arrive less often and sound lower. Frequency is measured in hertz, and the range we hear is roughly 20 Hz to 20 kHz. The other terms refer to different ideas: a circuit is an arrangement of components that allows electric current to flow; reflect means to bounce off a surface; absorb means to take in sound energy. So pitch is the best choice because it directly captures the attribute of a sound related to its perceived height or depth.
