![]() Noise Pollution Monitoring: Decibel meters are used to measure and monitor noise levels in urban areas, industrial areas, construction sites and other environments to identify pollution issues.These are the following uses of decibel meter: So many people can use smartphones to measure sound in their environment that can help them to protect their ears.Ī decibel meter is used to measure sound levels and is commonly employed in various applications.There are apps that can also be used to measure sound on a smartphone.It gathers sound samples, measures them and gives readings. ![]() The device which is used to measure sound is called decibel meter also called sound-level meters.

It should be noted that dеcibеls arе a relative scalе that doеs not immediately corrеspond to a physical quantity.In acoustics, thе rеfеrеncе lеvеl is frеquеntly set at the human hеaring thrеshold, which is roughly 20 micropascals (Pa) for sound prеssurе.Typically, thе rеfеrеncе lеvеl is determined by the context.The decibel (dB) is reflected in a logarithmic unit that is used to measure the loudness of sound.One decibel (0.1 bel) = 10 times the power ratio’s common logarithm.To book an appointment in Calgary or at another one of our clinics, contact us today.Sound is measured in decibel (dB), it is a unit which is used to express the ratio of two physical quantities, commonly acoustic or electric power, or to measure the relative loudness of sounds. Whether you need to have your hearing tested or have a hearing impairment and require hearing aids, our audiologists will be glad to help. Soundwave Hearing Clinic is proud to provide hearing solutions to residents of Calgary, Grande Prairie and surrounding areas. Keep in mind that the volume on most handheld devices goes up to 80dB and above. You should also avoid listening to music at high volumes, especially while wearing headphones. If you work in a noisy environment or often attend live concerts, it’s important to wear some form of hearing protection. ![]() For instance, you’re likely to experience permanent hearing loss after being exposed to a sound of 85dB for eight hours, but you risk permanent hearing damage after only 15 minutes of exposure to 100 dB. Hearing loss occurs as a result of how loud a sound is and how long you’re exposed to it. How high-decibel sounds cause hearing loss Here are the approximate decibel levels for some everyday sounds: Over the course of a day, you hear noises that register at all different points on the decibel scale, from wind rustling in the trees to cars honking in the streets. While decibels are most commonly used to measure sound, they also have applications as a measuring unit in the electronics and telecommunications industries. This is because the decibel scale was developed so that the first telephone companies could represent the amount of signal loss in phone lines. Each decibel involves an increase of approximately 26%, which is roughly the smallest change in sound that the ear can detect.Ī decibel is one-tenth of a bel, a rarely used unit named for Alexander Graham Bell, the inventor of the telephone. As a result, the decibel scale can range from 0 dB to 150 dB and still accommodate all the sound levels that humans hear. This means that a sound that’s 100 dB is not 10 times more intense than 10 dB, but rather 1,000,000,000 times more intense. On a logarithmic scale, values increase by powers of ten. If you tried to represent the full scope of human hearing using a linear scale, you’d need to use a range of sound levels from 0 to 100,000,000,000, which is far too vast to be useful. Decibels as a measure of sound intensityīecause human ears can hear noises with both very small and very large pressure waves, sound intensity needs to be measured using a logarithmic rather than linear scale. Keep reading to learn more about how decibels are calculated and what kinds of sounds can lead to hearing loss. In audiology, we use decibels when testing people’s hearing and identifying which sounds can damage human eardrums. A decibel is a unit of measure that compares two power levels, most often used when talking about sound intensity.
