Sound-level meters measure noise levels which are represented in decibels or dBA. The higher the noise level, the louder the noise. You can listen to sounds at 70 dBA or lower, as long as you want. Sounds at 85 dBA can lead to hearing loss if you listen to them for more than 8 hours at a time. Sounds over 85 dBA can damage your hearing faster. The safe listening time is cut in half for every 3-dB rise in noise levels over 85 dBA.
