What is an acceptable noise level in an office?

What is an acceptable level of noise?

Normal conversation is about 60 dB, a lawn mower is about 90 dB, and a loud rock concert is about 120 dB. In general, sounds above 85 are harmful, depending on how long and how often you are exposed to them and whether you wear hearing protection, such as earplugs or earmuffs.

What is the exposure standard for noise at a workplace?

85 dB
The WHS Regulations set the exposure standard for noise at an LAeq,8h of 85 dB(A) and a peak noise level at 140 dB(C), which protects most but not all people. Therefore, workplace noise should be kept lower than the exposure standard for noise if reasonably practicable.

How do I measure noise levels?

When you measure noise levels with a sound level meter, you measure the intensity of noise called decibel units (dB). A sound meter uses a display with a decibel range and resolution to approximate to the ear’s dynamic range, usually the upper range rather than the quiet part.

What is a typical noise level?

What is a safe level of sound?

Because people can’t hear all frequencies, or pitches of sound, A-weighted decibels (dBA) can be used to describe sound based on what human ears can actually hear. Sounds at or below 70 dBA are generally considered safe. Any sound at or above 85 dBA is more likely to damage your hearing over time.

How loud is 30db?

You’re right, you beat me to it . 30db isn’t very loud at all, really. People usually talk at around 50db or even 60db. People usually talk at around 50db or even 60db. So that’s 100-1000 times louder than 30db…
