The impact of boat related noise on marine life is a subject of concern, particularly for fish species that utilize acoustic communication for spawning purposes. The goal of this study was to quantify and examine the risk of boat noise on fish acoustic communication by performing acoustic monitoring of the May River, South Carolina (USA) from February to November 2013 using DSG-Ocean recorders. The number of boats detected increased from the source to the mouth with the highest detections near the Intracoastal Waterway (ICW). Boat noise frequency ranges overlapped with courtship sounds of silver perch (Bairdiella chrysoura), black drum (Pogonias cromis), oyster toadfish (Opsanus tau), spotted seatrout (Cynoscion nebulosus), and red drum (Sciaenops ocellatus). In the May River estuary, red drum may experience the greatest risk of auditory masking because of late afternoon choruses (21% time overlap with boat noise) and only one spawning location near the noisy ICW.

Anthropogenic noise pollution has been accelerating at an alarming rate, greatly altering aquatic soundscapes. Animals use various mechanisms to avoid acoustic masking in noisy environments, including altering calling rates or the frequency (pitch) of their vocalizations or increasing the amplitude (loudness) of their vocalizations (i.e.

Fishes and aquatic invertebrates utilize acoustic particle motion for hearing, and some additionally detect sound pressure. Yet, few underwater soundscapes studies report particle motion, which is often assumed to scale predictably with pressure in offshore habitats. This relationship does not always exist for low frequencies or near reflective boundaries.

Article Synopsis
- Noise-induced hearing loss (NIHL) is a significant occupational health issue globally, with a 16% prevalence, and is particularly concerning among Malaysian Armed Forces personnel, especially marine technicians in the Royal Malaysian Navy (RMN), who are at a heightened risk due to prolonged exposure to hazardous noise levels.
- A study conducted with 127 marine technicians from RMN revealed a high prevalence of occupational NIHL at 29.9%, with various factors such as age over 30, household income, military rank, and length of service being significantly associated with the risk.
- The research utilized questionnaires and pure tone audiometric assessments to diagnose NIHL, highlighting the need for awareness and preventive measures within this occupational group.
