- Wavelet has added a new feature called equal loudness that makes all frequencies equally loud.
- This is helpful because, when you lower the volume of your music, low and high frequencies start to dip more than mid frequencies.
- To celebrate the update, the developer has given us 100 promo codes to give away.
There are a lot of factors that affect the audio quality of the music you’re listening to, many of which simply can’t be fixed without shelling out more money on new hardware. However, there are ways to improve your listening experience without buying new hardware, such as by learning how to equalize (EQ). One of the best equalizer apps for Android is called Wavelet, and with its most recent update, it’s added a feature that fixes a problem you probably didn’t know existed.
The need for equal loudness
Back in the 1930s, a pair of scientists named Harvey Fletcher and Wilden A. Munson measured how loud a sound at one frequency needs to be in order for it to be perceived as equally loud as a sound at another frequency. These measurements were put together into graphs known as the Fletcher-Munson curves, and they showed that humans perceive certain frequencies as louder when the actual loudness of the sound decreases (and vice versa). In 2003, the Fletcher-Munson curves were revised and codified into the ISO 226 standards document, which outlines the “combinations of sound pressure levels and frequencies of pure continuous tones which are perceived as equally loud by human listeners.”
