...Vladimir V. Popov; Alexander Ya. Supin; Viatcheslav V. Rozhnov; Dmitry I. Nechaev; Evgenia V. Sysueva The influence of fatiguing sound level and duration on post-exposure temporary threshold shift (TTS) was investigated in two beluga whales ( Delphinapterus leucas ). The fatiguing sound was half...

... phalloidin and DAPI labeling to visualize hair cell bundles and nuclei. A TUNEL assay was used to identify apoptotic cells. Following noise exposure, goldfish exhibited a significant temporary threshold shift (TTS; ranging from 13 to 20 dB) at all frequencies tested(from 0.2-2 kHz). By 7 days post-exposure...

...Michael E. Smith; Andrew S. Kane; Arthur N. Popper SUMMARY Mammals exposed to loud aerial sounds exhibit temporary threshold shifts(TTS) that are linearly related to increases of sound pressure above baseline hearing levels. It was unknown if this relationship held true for aquatic ectotherms...

... not produce long-term physiological stress responses in goldfish, but a transient spike in plasma cortisol did occur within 10 min of the noise onset. Goldfish had significant threshold shifts in hearing after only 10 min of noise exposure, and these shifts increased linearly up to approximately 28 dB after...
