Define Sabines formula

• Sabine's formula is a tool to calculate the reverberation time of a room.
• Reverberation time is how long it takes for the sound in a room to decrease by 60 decibels after the sound source has stopped.
• The formula uses three main factors to calculate the reverberation time: the volume of the room, the total surface area of the walls, ceiling, and floor, and the average sound absorption of the room's surfaces.
• By considering these factors, the formula can predict how sound will behave in a room and how long it will linger.
• This information is useful for architects, engineers, and acousticians who design and build spaces for different purposes, such as speech, music, or theater.
