Online Sound Meter

Use the sound meter to determine how loud it is around you. When using the online hearing test or online audiometer to check your hearing, the test results are more accurate the more quiet it is around you. Ideally, the environmental sound level should be below 40 dB. Once it gets higher than 50 dB, the accuracy of the hearing test starts to quickly degrade with results showing more significant hearing loss then is truly present.

To start the sound meter, press theplay_arrowplay button (thepausepause button pauses while the cancel button resets everything). You will be prompted to give permission for the program to access your device's microphone. The central number provides a rough estimate of the instantaneous loudness level present in the room with anything less than 40 dB indicating a very quiet room. The dB reading is rough mainly because the microphone itself is not calibrated with sensitivity/gain widely inconsistent among different devices. The color of the box provides an idea of how quiet the room is as well:

• Green being anything less than 40 dB. Score: Excellent

• Blue being loudness levels between 40 - 50 dB. Score: Good

• Orange being loudness level between 50 - 60 dB. Score: Not Good

• Red being anything greater than 60 dB. Score: Poor

In any given home, the most quiet place to perform a hearing test accurately will be inside a closet full of clothes. No joke!

If you own a professional sound meter (~ $25) or acoustic calibrator (~ $150), you can manually calibrate the sound meter (click the grey bar) using the plus and minus buttons. This calibration is saved on your computer/device as a cookie and would have to be repeated if cookies are deleted and/or browser cache cleared.

Watch video of how to perform a headphone calibration using a sound meter.

If the sound meter is manually calibrated to perfection, it can also now be used to more accurately calibrate the headphones before starting the hearing test too! Place the headphones over the microphone and play the calibration file below. Keep adjusting the volume manually on your device's keyboard or headphone so that it averages around the specified decibel ± 3 dB (do not digitally adjust the volume which should be kept at the maximum setting). Obviously, this method of calibration only works if the sound meter is accurately calibrated first.
