This information can be confusing or overwhelming because most people are not familiar with sound levels and how loud a decibel sounds, or at what point noise exposure could lead to the need for hearing aids. It is important to understand exactly what a decibel is. A decibel is a unit of intensity of sound, abbreviated dB. The decibel scale is logarithmic, meaning it increases by the power of 10 each time. The smallest audible sound is 0 dB. A sound that is 10 times more powerful is 10dB, a sound that is 1, times more powerful is 30 dB, and so on it helps to count the zeroes in the scale to keep track!

55 decibels sounds like

From the lowest sounds perceivable to humans dB to those that can cause instant hearing loss dB , we use the decibel scale to define loudness. Decibel levels vary depending on the intensity of a sound and all sounds have specific decibel levels. Read on to learn all about it. On the decibel scale, it is in the lower range. Considering that 0 dB is the threshold of human hearing, and dB is the threshold of pain, sounds reaching 55 dB are considered mild and not harmful to human hearing. Below you can find a graphic listing decibel level thresholds as well as examples of common sounds of different intensities:. In fact, it is comparable to a quiet home environment, a residential street, or a normal conversation between two people. Since it is under 70 dB, it is not considered a harmful noise level. All sounds under 70 dB are considered safe for human hearing according to the Environmental Protection Agency. According to EPA recommendations, keeping your noise exposure under 70 dB over a period of 24 hours can help you prevent noise-induced hearing loss or hearing damage in the long term. However, it is also 18 times softer or less loud than an average rock concert, a lawnmower, or a scream dB. On the other hand, your distance from the source will also affect how loud a sound is.

Decibels are the unit of measurement for sound, abbreviated dB. Sounds at or below 70 dB are considered safe for our hearing. Like the Richter scale for measuring earthquakes, the decibel scale is logarithmic. This means that loudness is not directly proportional to sound intensity. Instead, the intensity of a sound grows very fast. A sound at 20 dB is 10 times more intense than a sound at 10 dB, and would be perceived as twice as loud. This workplace limit is also not safe for children, whose auditory system is still developing, and their ears have to last a lifetime. We recommend following the Centers for Disease Control and Prevention guidelines averaging no more than 70 dB. Headphones and earbuds can reach as loud as dB or more, so a safe level is 50 to 60 percent of the maximum volume. This helps protect our hearing and allows us to listen to our favorite music for longer.

Sounds humans can tolerate sounds that have pressure amplitudes that are many millions of times larger than the quietest sounds we can hear. Loud sounds can have intensities that trillions of times that of quiet sounds. Sound levels use the math of logarithms to compress these wide-ranging numbers into something manageable. Examples of logs in science include the pH scale for acids and bases in chemistry , the Richter scale for earthquakes and decibel for sound. There are two common nearly identical log scales for expressing sound amplitude: s ound intensity level SIL and sound pressure level SPL. Sound pressure is not the same thing as sound pressure level and so on. Sound levels are expressed in decibels. Sound levels for common sounds cover a range of about dB. See chart below for sound levels for common sounds.

Quiet rural area. On the other hand, your distance from the source will also affect how loud a sound is. The easiest way to check the loudness of a sound is to use a sound-level meter app like Decibel Pro. From the lowest sounds perceivable to humans dB to those that can cause instant hearing loss dB , we use the decibel scale to define loudness. Upper 70s are annoyingly loud to some people. Food blender 88 dB ; milling machine 85 dB ; garbage disposal 80 dB. Most people do not have prolonged exposure to the sound of a subway train, but many face occupational noises that are equally as loud all day long. Passenger car at 65 mph at 25 ft 77 dB ; freeway at 50 ft from pavement edge 10 a. It is important to understand exactly what a decibel is. On the decibel scale, it is in the lower range.

It is also the sound of a dishwasher or a vacuum cleaner. In general, 55 dB is considered a relatively loud noise level.
