Hush kit for the Pratt and Whitney JT8D-1 through -17 engines Two JT4As installed on a KLM DC-8. A hush kit is an aerodynamic device used to help reduce the noise produced by older aircraft jet engines. These devices are typically installed on older turbojet and low-bypass turbofan engines, as they are much louder than later high-bypass ...
The internal electronic circuitry of an active noise-canceling mic attempts to subtract noise signal from the primary microphone. The circuit may employ passive or active noise canceling techniques to filter out the noise, producing an output signal that has a lower noise floor and a higher signal-to-noise ratio .
Active noise control (ANC), also known as noise cancellation (NC), or active noise reduction (ANR), is a method for reducing unwanted sound by the addition of a second sound specifically designed to cancel the first.
Though the audio production company Defacto Sound, which is owned by Taylor, is the production headquarters for Twenty Thousand Hertz, he has said that the podcast is not intended as content marketing. [2] Instead of focusing on the industry of sound design exclusively, episodes focus on a variety of topics related to sound.
Dynamic noise limiter (DNL) is an audio noise reduction system originally introduced by Philips in 1971 for use on cassette decks. [10] Its circuitry is also based on a single chip. [22] [23] It was further developed into dynamic noise reduction (DNR) by National Semiconductor to reduce noise levels on long-distance telephony. [24]

The position of the pop filter is different in different recording situations, with a further position from the microphone causing fewer pop sounds. More distance means increasing the microphone gain and gaining more room noise. Normally, to get good quality, the pop filter should be placed about 2–6 inches (5–15 cm) away from the ...
A Soundfield microphone kit, consisting of the microphone and a signal processor, produces two distinct sets of audio signals called A-Format and B-Format. The sound processor may be either dedicated hardware, or a computer running software. The software processing may be done in real-time during the recording, or later offline.
