# Can you tell that your roommate turned up the sound on the TV if itsaverage 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.

See the step by step solution

## 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.
