How to Test Your Room for Echo
Updated October 2026
A clap test tells you how much echo your room has. Clap once and listen for the tail. A long, ringing tail means a hard room; a short tail means a soft one.
The short version
- Clap once, clearly, and listen to the tail of the sound.
- A long ringing tail means echo; a short one means the room is soft.
- Try the test in a few spots, and pick the one with the shortest tail.
- Add soft surfaces behind and beside the mic, and test again.
The clap test
Stand where you will record, and clap once. Record the clap, or listen to it live, and hear how long the sound lasts. A clean room has a short tail; a hard room rings.
Try spots
Try a few spots: a corner, a wardrobe, the middle of the room. Pick the one where the tail is shortest.
Soften
Put rugs, curtains, cushions and clothes on the hard surfaces behind and beside the mic. Clap again. The reverb and echo explanation covers what you are hearing.
Soften the room, then record
A soft room cuts echo at the source. Tunedzy can reduce what remains in the file.

Frequently asked questions
Is a clap test accurate?
It is a practical guide, not a measurement. It shows whether a room is soft or hard.
Where is the best spot?
Often a corner with soft things around, or a wardrobe of clothes.
Should I buy acoustic panels?
Only after soft furnishings. They often do most of the work.
