Final answer:
Common sound levels at 10 dB include running fingers through your hair, at 50 dB the sound inside a quiet home with no TV or radio, and 100 dB can be exemplified by the take-off of a jet plane. These levels help assess the intensity and impact of everyday noises.
Step-by-step explanation:
The question refers to identifying common sounds at levels of 10 dB, 50 dB, and 100 dB. To understand this, we should be familiar with the decibel scale, which measures the intensity of sound.
- 10 dB is a very low sound, comparable to running fingers through your hair. It's a subtle sound that most people would find barely audible.
- 50 dB is the noise level you might find inside a quiet home when there is no television or radio playing. This level of sound is comfortable and not disruptive to most people.
- At 100 dB, we are dealing with a much louder sound, like the take-off of a jet plane. This is a level of noise that can be harmful to the ears if one is exposed to it for prolonged periods.
Understanding these common sounds helps in gauging the intensity and potential impact of various noises we encounter in everyday life.
