Question

if the loudness is 3:4 then what will be amplitude and frequency

Answer 1

wrong question bro see it again and write it

Answer 2

ANSWER :

Amplitude is 3² : 4²

                    = 9 : 16

Frequency is 3 : 4

How ? look at the factors on which loudness depends                    

Definition :

Loudness is the characteristic property by which can distinguish two sounds of the same frequency and pitch.

We can distinguish between a faint sound from a loud sound using the property .

Factors affecting loudness

• Loudness is directly proportional to the square of amplitude .

• Loudness is inversely proportional to the square of distances.

• Loudness is directly proportional to the surface of a vibrating body.

• Loudness is directly proportional to the density of the medium.

Loudness is measured in decibels.

A sound having more than 120 dB is considered to be a noise pollutant .
