Understanding what we hear helps us understand what is there.
use artificial intelligence and algorithms to measure external frequencies and generate inverse waves to cancel them out, allowing them to isolate the wearer from the noise around them. The average frequency range of human hearing is 20 – 20,000 Hz., who proved the existence of electromagnetic waves. equates to sound’s volume or intensity. Using our ocean analogy—because, hey, it works—amplitude describes the height of the waves.
We measure amplitude in decibels . The dB scale is logarithmic, which means there’s a fixed ratio between measurement units. And what doesmean? Let’s say you have a dial on your guitar amp with evenly spaced steps on it numbered one through five. If the knob is following a logarithmic scale, the volume won’t increase evenly as you turn the dial from marker to marker. If the ratio is 4, let’s say, then turning the dial from the first to the second marker increases the sound by 4 dB.
Timbre is determined by the unique harmonics formed by the combination of notes in a chord. The A in an A chord is only its fundamental note—you also have overtones and undertones. The way these sound together helps keep a piano from sounding like a guitar, or an angry grizzly bear from sounding like a rumbling tractor engine.
But we also rely on envelopes, which determine how a sound’s amplitude changes over time. A cello’s note might swell slowly to its maximum volume, then hold for a bit before gently fading out again. On the other hand, a slamming door delivers a quick, sharp, loud sound that cuts off almost instantly. Envelopes comprise four parts: Attack, Decay, Sustain, and Release. In fact, they’re more formally known as ADSR Envelopes. This is how quickly the sound achieves its maximum volume.
