The intensity of sound high as a multiple of the average minimum threshold of hearing intensity is related to the decibel level D or loudness of sound according to I=10^D/10 (A) express 10^D/10 using radical notation 10^D/10= (B)The background noise level of a relatively quiet room has a decibel reading of 31. Find the intensity of this noise level round your answer to decimal places (C)a decibel reading of 132 is at the threshold of pain. if I2 is the intensity of the threshold and I1 is the intensity found and part B express or a show I2/I1 as a power of 10 I2/I1=10^ approximate the ratio(round your answer to two decimal places) _____x10^10
Properties of sound
A sound wave is a mechanical wave (or mechanical vibration) that transit through media such as gas (air), liquid (water), and solid (wood).
Quality Of Sound
A sound or a sound wave is defined as the energy produced due to the vibrations of particles in a medium. When any medium produces a disturbance or vibrations, it causes a movement in the air particles which produces sound waves. Molecules in the air vibrate about a certain average position and create compressions and rarefactions. This is called pitch which is defined as the frequency of sound. The frequency is defined as the number of oscillations in pressure per second.
Categories of Sound Wave
People perceive sound in different ways, like a medico student takes sound as vibration produced by objects reaching the human eardrum. A physicist perceives sound as vibration produced by an object, which produces disturbances in nearby air molecules that travel further. Both of them describe it as vibration generated by an object, the difference is one talks about how it is received and other deals with how it travels and propagates across various mediums.
The intensity of sound high as a multiple of the average minimum threshold of hearing intensity is related to the decibel level D or loudness of sound according to
I=10^D/10
(A) express 10^D/10 using radical notation
10^D/10=
(B)The background noise level of a relatively quiet room has a decibel reading of 31. Find the intensity of this noise level round your answer to decimal places
(C)a decibel reading of 132 is at the threshold of pain. if I2 is the intensity of the threshold and I1 is the intensity found and part B express or a show I2/I1 as a power of 10
I2/I1=10^
approximate the ratio(round your answer to two decimal places)
