    "It's a remarkable app for me since I use this in my research as a noise assessment tool. I recommend this because it's really accurate. "

WHAT’S THE MEANING?

A decibel is a unit of measurement that is being utilized to compare various different things such as sound or electricity. Consequently, the loudness or quietness of a sound is measured in decibels (dB) through a decibel scale. Another important concept to understand is the intensity of a sound. Intensity is defined as the amount of energy carried by a sound wave. Interestingly, notice that car engines produce extreme noise because the sound waves that are generated carry more energy.

DID YOU KNOW?

Did 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. 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. 

Before 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. 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. Over the years, the painstaking process of Foley was alleviated—thanks to digital sound makers.

    "I decided to take my young daughter to an outdoor concert this year, and wanted to make sure that we stayed far enough from the stage that I would not be risking damage to her hearing. I used SoundMeter on my iPhone and was able to confidently gauge how far away I needed to be. Thanks!"
