Question

measured independently at the position of a receiver, two speakers are measured to have sound intensity levels of 87.0 db and 83.6 db, respectively. when both speakers emit sound simultaneously, what sound intensity level is detected?select answer from the options below88.6 db 90.4 db 3.4 db171 db 85.3 db

Answer 1

When both speakers emit sound simultaneously, the sound intensity level detected is 170.6 dB. Therefore, the correct option is D

Step-by-step explanation:

The sound intensity level is measured in decibels (dB) and is given by the equation:

IL = 10 * log(I/I0)

Where IL is the sound intensity level, I is the sound intensity, and I0 is the reference intensity.

When two speakers emit sound simultaneously, the resulting sound intensity level is obtained by adding the individual sound intensity levels. Therefore, the sound intensity level detected when both speakers emit sound simultaneously is:

87.0 dB + 83.6 dB

= 170.6 dB
