A decibel (dB) meter is a device that records and measures the intensity of soundwaves. While dB meters are typically handheld or standalone devices, you can use your computer as a dB meter using dB meter freeware, such as the Digital Level Meter, Waveseeker, or Decibel Meter programs. These programs will enable you to treat your computer as a fully-functional dB meter in no time.

Save the download to your desktop for safe keeping.
Double click on the installation file to install the program.
Restart your computer.
Connect a microphone to your computer and open the program to begin recording and analysing soundwaves in your vicinity.
