In this review, we describe a variety of mechanisms that bacteria use to regulate transcription elongation in order to control gene expression in response to changes in their environment. Together, these mechanisms are known as attenuation and antitermination, and both involve controlling the formation of a transcription terminator structure in the RNA

Hearing protector attenuation: Models of attenuation distributions
The Journal of the Acoustical Society of America, 2002Current hearing protector rating standards estimate the protection performance for a given frequency as the mean attenuation minus a multiple of the standard deviation. Distributions of real-ear attenuation at threshold data are fit with maximum likelihood estimation procedures using both normal and mixed-normal models.

An impact attenuator is a device used to protect a vehicle from damage during a collision, thus preventing the risk of injury to the driver and passengers. Attenuators are used both on public roads and on racetracks as well as built into the vehicles themselves.
