SUMMARY
The sound intensity level of five trumpet players at 75 dB increases to approximately 96 dB when the number of players increases to 30. This calculation is based on the logarithmic relationship between sound intensity and perceived loudness, where an increase in intensity by a factor of 10 results in a perceived loudness increase of about 2 dB. The formula used is Beta = (10 dB) log10(I/I0), with I0 defined as 1.0 x 10^-12 W/m². The intensity ratio of 30 to 5 trumpet players is calculated as 6, leading to the final decibel level.
