You need to be conscious of your hearing and not put it at risk by being in an area where the noise level is too high. How loud is too loud? It all depends, but generally if you are near sound as loud as 130 decibels you should be very cautious, especially if it lasts for even just a few seconds.

How do you Calculate Maximum Noise Exposure Time?

Sound waves can be very dangerous for a person's wellbeing if they are too strong. Certain decibel rating can be withstood by the human body for very long without any risk of injury while on the other hand, there are levels of sound that should be avoided completely or limited to as little as possible. The formula for calculating how long you can be exposed to a certain decibel level is simple. It is the value you get after multiplying the time exposed to the sound by the time factor. Here is the formula for calculating the time factor:

Where:
  • TF = Time factor

  • RL = Reference level (85)

  • NL = Noise level (in decibels)

Understanding Your Results

Your results will be shown simply stating the amount of time that you can likely safely be exposed to a certain level of decibels. There are some shortcomings with this tool such as being able to gauge the importance of an indoor or outdoor setting, the use of ear protection, and other variables.

How to Use the Maximum Noise Exposure Tool

If you are worried about putting your hearing and wellbeing at risk potentially you can use this tool to help get a better idea of that. This tool will easily calculate how long you can approximately be exposed to certain noise levels. To use the tool you must:

  1. Enter the amount of decibels.

  2. Hit the calculate button and instantly get your answer.

Calculation Example

Let's say you are remodeling your kitchen. The use of power tools and heavy tools is something that worries you for your hearing and overall wellbeing. You need to use the tools but want to make sure you are not possibly overexposing yourself so you can use this tool to identify how long you may be safe to be around these noises. With your best estimate you believe the noise level you are going to be exposed to is 100 decibels.

To use this tool all you have to do is now enter 100 into the lone field on the tool. You can now hit calculate and get your maximum recommended noise exposure of 15 minutes. That means you may be safe to be exposed to 100 decibels of noise for 15 minutes, any longer may be harmful to you. This number is not definitive and should not be relied on with 100% accuracy. There is always the chance of injury with loud noises.

Noise Exposure (Noise Pollution) - Frequently Asked Questions

Noise pollution refers to the unwanted or undesired loud sound that comes from your surroundings that can have an impact on your well-being.

A decibel is the unit of measurement for how loud sound is.

50 dB is not very loud and is safe to be around for as long as you'd like to be around it. 50 dB is about how loud light traffic can be when standing next to the road or how loud a fridge can be.

A dog's bark can be a wide range of decibels, it depends on the breed. Generally, a dog bark will fall between 60 and 170 decibels.

A gas-powered lawn mower will likely be around 85 to 95 decibels depending on the model. This may be harmful to be exposed to for extended periods of time, so wearing proper hearing protection would be smart.

The decibel range for a human screaming is typically around 80 to 125 decibels.

Dependent on the situation and your proximity to the origin of the noise, thunder may be as loud as 125 decibels in many situations.

According to sound experts online, 200 decibels can be potentially lethal levels of sound.
