Opasanus tau, the Oyster Toadfish inhabits estuaries along the Atlantic coast. Males produce a short, harmonic mating call titled a 'boatwhistle' to attract females from late May to early August. A hydrophone was deployed under the dock at the Marine Biological Laboratory in Woods Hole Massachusetts to passively monitor their mating behavior. An underwater speaker played boatwhistles at the toadfish at varied times throughout the day and season to determine the male response to hearing extraneous noise.

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.

This article describes a novel and interdisciplinary context for learning about real-world sound waves. The "song" of the Plainfin Midshipman Fish produces an acoustical wave that is periodic but not sinusoidal. This acoustical signal is the focus of active research in sound source localization by fishes, the effects of hormones on hearing systems and the elucidation of neural mechanisms involved in social acoustic communication. In this paper, we introduce the reproductive biology and bioacoustics of the midshipman fish. We describe the use of the advertisement "song" of the male fish to visualize and interpret the dramatically different displacement, velocity and acceleration waveforms; to explore the roles of pressure and particle motion in production and detection of acoustical waves; and to apply Fourier analysis to understand the implications of the frequency spectrum in the production, transmission and reception of sound in an aquatic environment.
