SOUND The loudness of a sound L in decibels is defined by L= 10 log. R, where R is the relative intensity of the sound. A chofr director wants to determine how many members could sing while maintaining a safe level of sound, about 80 decibels. If one person has a relative intensity of 10 when singing, then how many people could sing with the same relative intensity to achieve a loudness of 80 decibels?
