What is the decibel scale?

To express levels of sound meaningfully in numbers that are more manageable, a logarithmic scale is used, rather than a linear one. This scale is the decibel scale.

What Do Different Decibel Levels Mean?

Most sound within this range is practically inaudible. Sounds that produce decibel levels between 0 and 30 comprise whispers as well as the ticking of a watch.

What is the lowest decibel?

Since it’s logarithmic and relative, the decibel scale is also limitless in both directions and doesn’t stop at 0. Zero dB is theoretically the lowest limit of human perception, but in practice, a human will rarely be able to hear a sound below 10 dB.

What happens if you hear 140 dB?

Above 140 dB, sounds can cause humans physical distress: shortness of breath, nausea, nosebleeds, and other severe discomforts.

What is a decibel?

The decibel is the standard international unit used to measure volume. One decibel (1 dB) isn’t equal to anything that’s easy to describe in the real world — it comes from a complex equation involving pressure that we don’t need to get into right now.

Is 40 decibels a logarithmic or relative?

Instead, just remember that decibels are relative and logarithmic. Relative means that dB is only a useful measurement when compared to other dB values. Logarithmic means that, for every 10 dB, the corresponding real-world volume doubles. 40 dB is twice as loud as 30 dB, and half as loud as 50 dB.

Anything over 80 decibels can cause permanent hearing damage with lengthy exposure.

How Decibel Levels Are Measured

To measure the noise level of different sounds, we use a measurement unit called the decibel (dB). It represents a sound’s intensity. To measure a sound’s frequency, we use the hertz (Hz).

Decibel Level Chart of Common Sounds

The intensity of common sounds ranges from 0 dB to 140 dB. Looking at a decibel chart such as the one below, we can determine if those sounds are safe, potentially harmful, or outright dangerous for our ears.

Noise Level Chart and Maximum Exposure Time

The amount of time you are exposed to a certain decibel level will determine the potential of hearing damage or loss. While you can safely be exposed to some levels for a few hours, other levels can cause pain or even hearing loss if you are exposed to them for even one minute.

Tips to Prevent Damage to Your Hearing

Here are a few simple tips to prevent damage to your hearing you can apply if you find yourself in a situation where you are exposed to loud noises:

Measure the Sound Level Around You With Decibel Pro App

The easiest way to check the decibel readings of common sounds is to use a professional app like Decibel Pro. Using it, you can measure the sound levels around you and take measures to protect your hearing if necessary.

Maximal Noise Exposure: How to Use This Calculator

To use this noise pollution calculator, enter the noise level in deceibels (dB) and it will automatically calculate the maximum amount of time for safe exposure. You should never expose yourself more than this displayed time to protect yourself from hearing loss.
