Short Answer

Can you tell that your roommate turned up the sound on the TV if its

average sound intensity level goes from \({\rm{70dB}}\) to \({\rm{73dB}}\)?

Yes, it is possible to tell the roommate turned up the sound because the difference between sound levels is in noticeable range.

Step by Step Solution

TABLE OF CONTENTS

Step 1: Range of noticeable sound

At a given frequency, the difference between intensity sound levels \(3\,dB\) can is easily noticed.

Step 2: Explanation

Here, the difference in sound intensity level is also \((73dB - 70dB) = 3\,dB\). In this range, sound can be easily noticed and we can tell our roommate about loudness.

How do sound vibrations of atoms differ from thermal motion?

The amplitude of a sound wave is measured in terms of its maximum gauge pressure. By what factor does the amplitude of a sound wave increase if the sound intensity level goes up by\(40.0\;{\rm{dB}}\)?

A commuter train blows its \(200\;{\rm{Hz}}\)horn as it approaches a crossing. The speed of sound is\(335\;{\rm{m/s}}\). (a) An observer waiting at the crossing receives a frequency of\(208\;{\rm{Hz}}\). What is the speed of the train? (b) What frequency does the observer receive as the train moves away?

Question: (a) What is the intensity of a sound that has a level \(7.00\;{\rm{dB}}\) lower than a\(4.00 \times {10^{ - 9}}\;{\rm{W/}}{{\rm{m}}^{\rm{2}}}\)sound? (b) What is the intensity of a sound that is \(3.00\;{\rm{dB}}\)higher than a \(4.00 \times {10^{ - 9}}\;{\rm{W/}}{{\rm{m}}^{\rm{2}}}\)sound?

(a) A bat uses ultrasound to find its way among trees. If this bat can detect echoes 1.00ms apart, what minimum distance between objects can it detect? (b) Could this distance explain the difficulty that bats have to find an open door when they accidentally get into a house?
