Decibels (dB) are a way to measure how loud or quiet a sound is on the decibel scale. This scale helps us compare sounds, from whispers (around 20 dB) to normal conversations (about 60 dB) and even louder things like concerts (around 120 dB). The tricky part? It’s not linear; each 10 dB increase means the sound is actually 10 times more intense. Decibels help quantify sound levels using a logarithmic ratio of one unit of measurement to another, so simply put, it is a way to measure how loud or quiet something is. Decibels are typically measured in two ways in relation to hearing: dB SPL (Sound Pressure Level). dB SPL refers to the magnitude of displacement of molecules in the air.The decibel level of a sound source can be measured using a decibel meter, which is a simple device that displays the sound intensity in dB. To obtain accurate measurements, it is essential to place the meter at a distance of at least 20 feet from the generator and measure the noise levels from different angles and locations.The physical effects of intense sound are just one way to tell if the sounds you’re hearing may be unsafe for an extended period of time. Thankfully, there are a couple of ways to measure whether a sound you’re around is at a safe level. How to measure decibel levels.
