Soundwave is one of the characters from the original Transformers line. His alternate mode is a microcassette recorder and he has a distinctive monotone, computerized voice. [1] Soundwave is able to detect and jam transmissions across the entire energy spectrum, a talent that makes him suited to his position as a Decepticon Communications Officer.
A noise-cancellation speaker emits a sound wave with the same amplitude but with an inverted phase (also known as antiphase) relative to the original sound. The waves combine to form a new wave, in a process called interference , and effectively cancel each other out – an effect which is called destructive interference .
Headphones are a pair of small loudspeaker drivers worn on or around the head over a user's ears. They are electroacoustic transducers, which convert an electrical signal to a corresponding sound. Headphones let a single user listen to an audio source privately, in contrast to a loudspeaker, which emits sound into the open air for anyone nearby ...
Simplified graphical depiction of active noise reduction. To cancel the lower-frequency portions of the noise, noise-cancelling headphones use active noise control.A microphone captures the targeted ambient sounds, and a small amplifier generates sound waves that are exactly out of phase with the undesired sounds.
Whether you're at the gym or working on a video editing project at your desk, these noise cancelling, wireless headphones make things easy and crystal clear. $159 at Walmart.
Audiograms of human hearing are produced using an audiometer, which presents different frequencies to the subject, usually over calibrated headphones, at specified levels. The levels are weighted with frequency relative to a standard graph known as the minimum audibility curve , which is intended to represent "normal" hearing.
