Sound Meter Pro: Sound Meter PRO works with Android phones to measure sound or decibel level. Below is a list of the most popular and highly rated apps for your phone available today for measuring sound. So in order to tell what decibel a sound reaches you need to use the very thing your ears are being damaged by-technology. And all of this is useful information, but most of today’s technology doesn’t come equipped with a decibel reader. Below is a chart for reference on just how long you can be exposed to certain decibels before they become harmful.Īnything over 106 can do damage fairly quickly. You can listen to 85 dB for about eight hours before it starts to damage your hearing. To help you understand better, a conversation between two people-assuming they are not shouting-is about 60 dB, a motorcycle is around 75 dB, and city traffic is around 85 dB. So to protect your hearing you need to know three things about a noise: how loud, how long (will you listen to it), and how close (will you get to it). But all of these factors depend on the first-the loudness decibel (dB) level.Ī decibel is a way to measure the loudness of sounds-the higher the number of a decibel the higher the sound. For every three decibel increase the chance for injury to hearing goes up and happens more quickly. Some sounds that are safe for ten minutes can become dangerous when listened to for an hour or more, especially if you are too close to them. And though you probably already wear ear protection at concerts or when you’re operating a jackhammer or waving out an F-35 fighter jet (Hey, it’s someone’s job), regular sounds like traffic and a hair dryer can also damage hearing if listened to for too long.īecause of the excessive noise from technology in today’s world we risk our hearing every day. In today’s noisy and technological world, our wonderful and useful ears are often exposed to loud and sometimes damaging sounds. Your ears didn’t evolve to deal with the constant sounds they are exposed to on a daily basis-not even those sounds you think aren’t “too bad.” So how can you know when to protect your tortured ears from the threat of random noise pollution? Well, there’s an app for that. Today we have a television in every room, and heck at a lot of gas station pumps. And it sure wasn’t this way 50 years ago. Over the years, the painstaking process of Foley was alleviated-thanks to digital sound makers.Believe it or not, the noisy technological world you now occupy wasn’t the norm even 25 years ago. For instance, did you know that lightsaber’s sound in the movie Star Wars was produced by the sound designer Ben Burtt using microphone feedback and buzzing motors? Moreover, the sound of laser blasts was made from hitting an antenna tower wire with a hammer. Surely, film connoisseurs out there are familiar with the terms “Foley studio”, “Foley Sheets,” Foley reels,” and “Foley editor” because they all take part in the reproduction of everyday sound effects that are incorporated within the filmed videos during the post-production stage of filmmaking.īefore the emergence of digital sound effects that are readily available, filmmakers back then utilized some techniques, some you might find ridiculous, that greatly helped to make movie scenes cinematic. DID YOU KNOW?ĭid you know that sound effects in films are called Foley? And the process of creating it is called the “Foley art”, named after the legendary developer of sound effects technique in filmmaking Jack Foley. Interestingly, notice that car engines produce extreme noise because the sound waves that are generated carry more energy. Intensity is defined as the amount of energy carried by a sound wave. Another important concept to understand is the intensity of a sound. Consequently, the loudness or quietness of a sound is measured in decibels (dB) through a decibel scale. A decibel is a unit of measurement that is being utilized to compare various different things such as sound or electricity. ![]()
