# The sound of normal breathing is not very loud, with an intensity of about 11 db at a distance of 1 m away from the face of the breather. note that in this problem sound intensity in decibels is denoted β; intensity in w/m² is denoted i. given that a person with normal hearing canbarely detect a sound with intensity of 1 db at a frequency of 1khz (the sensitivity of the human ear peaking near 1 khz), how faraway could this person detect another person breathingnormally? express the distance in meters.
