Question

define the terms: vibrations , frequency and loudness​

Answer 1

Explanation:

vibration-- a periodic motion of the particles of an elastic body or medium in alternately opposite directions from the position of equilibrium when that equilibrium has been disturbed (as when a stretched cord produces musical tones or molecules in the air transmit sounds to the ear)

frequency-- The number of vibrations counted per second is called frequency

loudness-- loudness is the subjective perception of sound pressure. ... Loudness, a subjective measure, is often confused with physical measures of sound strength such as sound pressure, sound pressure level (in decibels), sound intensity or sound power

Answer 2

Answer:

1. Vibrations:- Vibration is the mechanical oscillations of an object about an equilibrium point.

2. Frequency:- Frequency is the number of occurrences of a repeating event per unit of time.

3. Loudness:- Loudness is a subjective term describing the strength of the ear's perception of a sound.
