Occupational noise exposure is the main risk factor for work-related hearing loss. One study examined hearing test results obtained between 2000 and 2008 for workers ages 18–65 who had a higher occupational noise exposure than the average worker. [153] Of the sample taken, 18% of the workers had hearing loss.
Hall v. Florida, 572 U.S. 701 (2014), was a United States Supreme Court case in which the Court held that a bright-line IQ threshold requirement for determining whether someone has an intellectual disability (formerly mental retardation) is unconstitutional in deciding whether they are eligible for the death penalty.

Progressive age-related loss of hearing acuity or sensitivity can start as early as age 18, primarily affecting the high frequencies, and men more than women. [6] Such losses may not become apparent until much later in life.
Noise-induced hearing loss is a permanent shift in pure-tone thresholds, resulting in sensorineural hearing loss. The severity of a threshold shift is dependent on duration and severity of noise exposure. Noise-induced threshold shifts are seen as a notch on an audiogram from 3000 to 6000 Hz, but most often at 4000 Hz. [16]
Hearing loss has multiple causes, including ageing, genetics, perinatal problems and acquired causes like noise and disease. For some kinds of hearing loss the cause may be classified as of unknown cause. [citation needed] There is a progressive loss of ability to hear high frequencies with aging known as presbycusis. For men, this can start as ...
The Death Penalty Information Center (DPI) is a non-profit organization based in Washington, D.C., that focuses on disseminating studies and reports related to the death penalty. Founded in 1990, DPI is primarily focused on the application of capital punishment in the United States .
[150] [151] The strength of phase locking to the temporal fine structure of signals (TFS n) in quiet listening conditions remains normal in peripheral single-neuron responses following cochlear hearing loss. [152] Although these data suggest that the fundamental ability of auditory-nerve fibers to follow the rapid fluctuations of sound remains ...
Florida, 458 U.S. 782 (1982) – The death penalty is unconstitutional for a person who is a minor participant in a felony and does not kill, attempt to kill, or intend to kill. Tison v. Arizona , 481 U.S. 137 (1987) – Death penalty may be imposed on a felony-murder defendant who was a major participant in the underlying felony and exhibits ...
