Simply start the app and clap your hands. IOS - ClapIR is a tool for measuring the acoustic properties of a room. Here are some of the best reverberation time apps: The app will analyze your sound data and provide estimated reverberation time. The app will instruct you to clap, but we find popping a ballon works better. Here is a video explaining how to use the FREE T60 CALCULATOR!Īnother option is reverberation time apps!Ī reverberation time app will often use your phone mic to record noise inside your room. You can open this with Microsoft excel or in Google sheets. Our other free reverberation time calculator is in the form of an excel spreadsheet. UPDATE: Check out our new and easy to use reverb calculator web app! However, many people prefer to use a reverberation time calculator.

You can find this by simply measuring the size of each surface in the room and finding the absorption coefficient of each material. This does not require any testing, microphones or speakers. The way we calculate reverberation time here is by using the total absorption of a room. ![]() ![]() ![]() ![]() A represents the total Absorption of the room.V represents the total Volume of the room.To find the reverberation time (T60) of a room we use the equation: A T60 of less than 0.5 seconds is ideal for good speech clarity. Reverberation Time is the time it takes for a sound to decay by 60 dB and is sometimes abbreviated T60 or RT60.
