How does distance impact listening and what is the 6 dB rule

This 6 dB rule example shows the impact of distance on listening. Sound loudness is measured in units called decibels, abbreviated as dB. When distance doubles (is greater), a speaker’s voice decreases by 6 decibels. When distance is halved (is less), the voice of the person speaking increases by 6 decibels. Moving closer makes the signal (voice or noise) louder. Moving away makes the signal quieter.

Following the 6 dB rule improves listening for anyone but especially individuals with hearing loss
