Attenuation (brewing)
In brewing, attenuation refers to the conversion of sugars into alcohol and carbon dioxide by the fermentation process; the greater the attenuation, the Apparent attenuation is calculated using the equation:
where AA is apparent attenuation and OG and FG are the original and final gravities.

What Is Sound Attenuation? [2024] - Soundproof Silence
Sound Absorption. During sound absorption, a sound wave is neither transmitted or reflected. Instead, the energy gets absorbed into the material. Three basic categories of sound absorbers exist. These include: Porous absorbers. Porous absorbers often consist of matted or spun fibers. Some common examples include: Carpets; Draperies; Spray ...

acoustic attenuation definition
In physics, attenuation or extinction is the gradual loss of flux intensity through a medium. For instance, dark glasses attenuate sunlight, lead attenuates X-rays, and water and air attenuate both light and sound at variable attenuation rates.

Attenuation distortion
Attenuation distortion is the distortion of an analog signal that occurs during transmission when the transmission medium does not have a flat frequency Attenuation distortion occurs when some frequencies are attenuated more than other frequencies.

Attenuation is dependent of frequency.
For example, the following is the Attenuation vs. Frequency for an RG-8 (coaxial) cable:

At 1Mhz the Attenuation is 0.1 dB for each 100 Feet.
