SOUND The loudness of a sound L in decibels is defined by L=10 log₁0 R, where R is the relative intensity of the sound. A choir 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 106 when singing, then how many people could sing with the same relative intensity to achieve a loudness of 80 decibels?
