The human temporary threshold shift after exposure to 60 minutes' noise in an aerobics class

Abstract

The potential hazard of noise to hearing is well documented. However, there are some experiences of noise-induced hearing loss (NIHL) that are not so well-known, for example the effects of leisure noise, and in particular, leisure noise experienced during an aerobics class. A preliminary study of the noise level in aerobics classes in the Manchester region was carried out and their mean noise level was found to be 89.6 dB(A) (+/-4.7 dB(A)). Pure tone thresholds in the audible frequency range were obtained from 28 young adult volunteers (mean age 21 years; standard deviation (SD) 2.3 years) and 14 subjects (the 'exposure' group) were then invited to join (but not participate in) an aerobics class (mean noise level 91.8 dB(A) (+/-1.5 dB(A)) for 60 minutes. The noise levels in the aerobics class were monitored throughout the 60 minutes and the subjects did not stray from a small marked area (2 m2). Subjects' hearing thresholds were obtained for a second time, beginning within 2 minutes of the cessation of the noise, and any temporary threshold shifts (TTS) were noted. A second group of 14 subjects (the control group) was invited for a second audiogram after at least 60 minutes, during which time subjects were not exposed to any no...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
