Industrial environments with high noise levels, like construction sites, can potentially damage workers’ hearing. Sound level meters that are used for acoustic measuring indicate noise levels in a workplace, and let workers know when it’s time to put on their PPE. According to OSHA, if noise level exceeds 85dB, they must put on personal hearing protection equipment to prevent hearing loss.
There are three important factors that can put you at risk of noise-induced hearing loss (NIHL): how far are you located from the noise source, how loud is the noise, and how long the noise lasts. Many common sounds may not seem harmful, like traffic or a lawn mower, for example. However, extended exposure even to low or medium levels of noise is as dangerous as the short exposure to an impulse noise, such as gunshots or fireworks. You risk facing permanent hearing loss, especially is you are close to the source of the sound.
Various working environments dictate what noise level measuring device to use. High noise pollution is characteristic of construction sites, factories, manufacturing plants, military maintenance, mining, transportation, and oil and gas industry. These worksites require powerful instruments, like sound examiners, to be used to ensure the high precision level in measuring noise levels in order to determine if the workers have to wear PPE. In potentially low noise pollution environments like stores, offices, and small repair shops, a noise indicator is a good cost-saving option. This affordable device alerts you when the noise level gets above 85dB, giving you the opportunity to protect your hearing by putting on ear plugs, ear muffs, or both if needed for extra protection.
The most up-to-date models of sound meters – the 3M SoundPro SL/DL Series and the 3M Sound Examiner Series SE401/SE-402 – are compatible with detection management software that will help you analyze the collected data and build reports.
We also offer a durable outdoor measuring system (OMS) that allows you perform unattended sound level monitoring, as the weatherproof case can be padlocked.
Employers are required by OSHA to measure noise levels at their workplaces, provide free annual hearing exams, hearing protection, and training for their employees, as well as conduct evaluations of the adequacy of the existing hearing protectors in use.
To comply with OSHA standards, shop our top hearing protection brands like 3M, E-A-R, Howard Leight, Moldex, and Pyramex. Here are a few suggestions worth checking out:
In addition to using PPE, engineering controls (such as lubricating noisy equipment), and administrative controls (like limiting the amount of time workers spend close to the source of noise) must be used to reduce employees’ exposure to noisy environment.
