- 5. A dB meter registers 124 dB when placed 2.50 m in front of a loudspeaker. Assuming uniform spherical spreading of the sound, how far away would the intensity level be a somehow reasonable 85 dB? mWhat sound level in dB is produced by earphones that create an intensity of 1.50 ✕ 10−2 W/m2? _____ dBThe sound level at a distance of 3.0 m from a source is 120 dB. a) At what distance will the soundlevel be 100 dB? b) At what distance will the sound level be 10 dB?
- The relative intensity of the first harmonic of a sound is 70 dB (1000 Hz). The second harmonic of a sound has the amplitude of a pressure 5 times smaller than that for the first harmonic. What is loudness for the second harmonic if we hear this sound separately?What is the decibel level of a sound that is twice as intense as a 100.0-dB sound?

- The sound level measured in a room by a person watching a movie on a home theater system varies from 50 dB during a quiet part to 90 dB during a loud part. Approximately how many times louder is the latter sound?6. You measure the intensity level of a sound wave 6 cm from its source (treat as a point source), and the result is 84 dB. What is the intensity of this sound wave? Answer:
