许多水生生物利用发声进行繁殖行为；因此，破坏它们的声景可能会对它们的生活史产生不利影响。雄蚝蟾鱼(Opsanus Tau)在春季在浅水中筑巢，并通过船哨的发声吸引雌鱼。雄鸟表现出很高的巢保真度，使它们在沿海水域容易受到人为声音的影响，这可能会掩盖它们的发声和/或降低听觉敏感度。此外，自行产生的船哨对蟾鱼听觉敏感度的影响尚未得到解决。为探讨声暴露对蟾鱼听觉敏感度的影响，采用听觉诱发电位测定了暴露前后(0天、1天、3天、6天和9天)连续回放1或12小时船用发动机声或同种发声前后的声压和颗粒加速度敏感性曲线。接触船哨对听觉敏感度没有影响。然而，暴露于人为声中至少3天会导致听觉敏感度显著下降，在人为声暴露1小时和12小时后，听觉敏感度分别立即移动8dBSPL和20dBSPL。了解自身产生的和人为的声音暴露对听觉敏感度的影响有助于深入了解音景如何影响声音交流。
Many aquatic organisms use vocalizations for reproductive behavior; therefore, disruption of their soundscape could adversely affect their life history. Male oyster toadfish (Opsanus tau) establish nests in shallow waters during spring and attract female fish with boatwhistle vocalizations. Males exhibit high nest fidelity, making them susceptible to anthropogenic sound in coastal waters, which could mask their vocalizations and/or reduce auditory sensitivity levels. Additionally, the effect of self-generated boatwhistles on toadfish auditory sensitivity has yet to be addressed. To investigate the effect of sound exposure on toadfish auditory sensitivity, sound pressure and particle acceleration sensitivity curves were determined using auditory evoked potentials before and after (0-, 1-, 3-, 6- and 9-day) exposure to 1- or 12-h of continuous playbacks to ship engine sound or conspecific vocalization. Exposure to boatwhistles had no effect on auditory sensitivity. However, exposure to anthropogenic sound caused significant decreases in auditory sensitivity for at least 3 days, with shifts up to 8 dB SPL and 20 dB SPL immediately following 1- and 12-h anthropogenic exposure, respectively. Understanding the effect of self-generated and anthropogenic sound exposure on auditory sensitivity provides an insight into how soundscapes affect acoustic communication.
