WebSeveral fish species use sounds to communicate and masking noise may impair signal exchange. Data from laboratory tests on hearing sensitivity in fish show that prolonged exposure to high-intensity noise can cause temporary hearing loss, which decreases the detection of short transient signals and the ability to resolve rapid changes in sounds. WebIntensity noise is usually understood to quantify fluctuations of the laser output power (not actually an optical intensity), and in most cases normalized to the average power. The measurement is based on …
