Question

The sound level produced by one singur is 70.6 db. what would be the sond level producod by a choros of 39 such singers (all singing .at the samme intensity at approximately the same (distance as the original singer)? answer in motte of dB.

Answer 1

When multiple sound sources are combined, the total sound level can be found using the formula:

Ltotal = 10 log10 (N) + Lsource

where N is the number of sound sources and Lsource is the sound level of each individual source.

In this case, we have 39 singers and each singer produces a sound level of 70.6 dB. Substituting these values into the formula, we get:

Ltotal = 10 log10 (39) + 70.6 dB

Ltotal = 10 (1.591) + 70.6 dB

Ltotal = 88.5 dB (rounded to one decimal place)

Therefore, the sound level produced by a chorus of 39 singers singing at the same intensity at approximately the same distance as the original singer would be approximately 88.5 dB.
