The volume of a room is length times width times height. So it goes with a reverberation chamber.
The volume of a reverberation chamber is calculated by length times width times height.
determine factor that affect the reverberation time of a room
A field
Reverberation
Volume of room in square feet * 0.0015
Some rooms have more, some have less.Here's how to calculate the volume of your own room:-- Measure the length of the room in meters.-- Measure the width of the room in meters.-- Measure the height of the room in meters.-- Calculate the product of all three numbers.-- Multiply the product by 1,000.-- The last number is the room's volume in liters.
Reverberation. Reflection of sound waves off of surfaces can lead to one of two phenomena - an echo or a reverberation. A reverberation often occurs in a small room with height, width, and length dimensions of approximately 17 meters or fewer.
The reverberation time for a room depends on the ratio of the volume of the room to the total effective absorbing area of the room. The effective absorbing area will depend on the materials which make up the room and which are in the room. The effective absorbing area will depend on frequency. As an example, if a wall absorbs 30% of the sound (at a given frequency) for each reflection, the effective area for the wall will be 0.3 times the actual area of the wall. There are tables of typical effective areas, often reported in "sabins," for other objects, such as people, chairs, etc.
N=60*fresh air/volume(room)
It is because in a furnished room, reverberation occurs less than in a room with no furnishing.
You need to measure it. You cannot calculate it from the available information.
to calculate a room's capacity is very simple. this is basically trying to find the 'volume' of the room. just multiply the height, the width, and the length together
