Sound level meter is a type of electronic device that is widely used for measuring sound pressure levels in a particular area. It also allows users to determine the acoustic intensity and determine if an environment is so loud that it could actually damage a human’s hearing.
These devices are widely used at construction sites and in manufacturing facilities, where loud heavy machines are used and can be a real threat to workers’ hearing, who are exposed to loud sounds on a daily basis. Also, many sports arenas and stadiums use sound level meters to measure the sound level of the crowd noise.
Sound level meter online and offline retailers sell measures in decibels. The threshold of hearing is 0.0 dB-SPL, which is equal to 20 uPa (micro Pascals). This is the same sound level that a person would perceive if in a deep cave or a large chamber. A typical model of sound level meter measures between 60-70 dB, while human’s hearing can get damaged at a sound level of 90 dB. Slight damage to hearing can occur before the sound becomes so loud that you will feel a physical pain.
So how can you know when the sound level is over the normal? Easily, you just check the sound level meter.
Usually, sound level meters are designed as single-function hand-held devices. They are intended to be held at arm’s length during measuring, so it can reduce the effects of the body on the measurements (provide more accurate measurements). In many countries, safe sound levels are a must in many different working environments. Aside from ensuring a safe working environment, sound level meters are also used for testing sound levels when setting up speakers for public address systems. Using this device, you can ensure that everyone in the crowd hears the speaker clearly with no hearing threats.
Most models of sound level meter online retailers offer are powered by batteries and come in the size of a cell phone. They feature a large microphone and can either have an analog or digital display to show the measurements. Basic models of sound level meters can be found with a price tag of about $50, while the more advanced, more innovative models are more expensive. Also, these models have a greater sensitivity and can log multiple measurements for larger sites. But if a basic measurement of sound level is what you need, go with simpler device which are not as expensive.
