Question
Your ears are sensitive to differences in pitch, but they are not very sensitive to differences in intensity. You are not capable of detecting a difference in sound intensity level of less than 1 dB. By what factor does the sound intensity increase if the sound intensity level increases from 60 dB to 61 dB

Answer:
1.29
Explanation:
The level of intensity of sound (β) (in decibels, dB) is given by:
β =
, where I = sound intensity in watts per meter squared and
= reference intensity.
Change in sound intensity level (Δβ) =
= 61 – 60 = 1
Δβ =
= 1
Hence, the sound intensity will increase by a factor of 1.29.
