“…The answer to the question, 'What do fish listen to?' is 'all sounds', including what is termed 'ambient noise' [Rogers, 1986;Rogers et al, 1989;Lewis and Rogers, 1992].…”

The literature on fish hearing has increased significantly since our last critical review in 1973. The purpose of the current paper is to review the more recent literature and to identify those questions that need to be asked to develop a fuller understanding of the auditory capabilities and processing mechanisms of fishes. We conclude that while our understanding of fish hearing has increased substantially in the past years, there are still major gaps in what we know. In particular, the comparative functional literature is extremely limited, and we do not yet know whether different species, and particularly hearing specialists as compared to hearing nonspecialists, have fundamentally different auditory capabilities and mechanisms.

“…A preliminary study showed goldfish could detect simulated scattered ambient noise in an ambient noise masker (Rogers et al, 1989). In this study, two goldfish (about 15 an in length) were classically conditioned to suppress their heart rate upon presentation of an acoustic stimulus simulating the scattered noise.…”

“…A second preliminary experiment, shown in Figure 7, was conducted to show that goldfish could detect simulated scattered ambient noise in a noise masker (Rogers et al, 1989). In this experiment, threshold of the scattered noise as a function of distance from the fish was determined using classical heart rate conditioning.…”

The present goals of this research project are to (1) determine the characteristics of 1.0 noise scattered by the swimbladder of the goldfish and the oscar, (2) develop a method to 0 reproduce the scattered signal using signal generators, filters, and underwater transducers, and (3) measure the ability of the fish to discriminate this signal from simulated scattered noise. O This research project has progressed in three major areas this past year: a more comprehensive C t') literature review on fish hearing, improvements in the system used to measure the response of C a fish's swimbladder to low frequency sound, and the acquisition of additional equipment < needed for measuring the ability of a fish to detect scattered ambient noise. Literature Review A library of over 200 journal articles and 7 books relevant to fish hearing was compiled for reference. One result of this review was the drafting and successful defense of a Ph.D. thesis proposal. Swimbladder Response The majority of the effort in the past year was spent on refining the NIVAMS (Non-Invasive Vibration Amplitude Measurement System) to provide better accuracy and repeatability. In review, the NIVAMS uses low power continuous wave ultrasound to detect the motion of the swimbladder of a fish in vivo. The motion of the swimbladder introduces sidebands into the spectrum of the reflected signal. NIVAMS uses a HP 3585A spectrum analyzer to measure the relative amplitudes of the carrier frequency and these sidebands. From this data, the motion of the target can be determined.
