“…Among the sources of anthropogenic impact, acoustic pollution is increasingly becoming a threat for natural communities worldwide 4 . This human disturbance has already been shown to negatively affect acoustic communication in many animal groups, such as insects 5 , fish 6 , birds 7 , reptiles 8,9 , amphibians 9–12 and mammals 13,14 , as well as influencing species persistence and conservation 4 .…”

Anthropogenic disturbance is a major cause of the biodiversity crisis. Nevertheless, the role of anthropogenic substrate vibrations in disrupting animal behavior is poorly understood. Amphibians comprise the terrestrial vertebrates most sensitive to vibrations, and since communication is crucial to their survival and reproduction, they are a suitable model for investigating this timely subject. Playback tests were used to assess the effects of substrate vibrations produced by two sources of anthropogenic activity– road traffic and wind turbines– on the calling activity of a naïve population of terrestrial toads. In their natural habitat, a buried tactile sound transducer was used to emit simulated traffic and wind turbine vibrations, and changes in the toads’ acoustic responses were analyzed by measuring parameters important for reproductive success: call rate, call duration and dominant frequency. Our results showed a significant call rate reduction by males of Alytes obstetricans in response to both seismic sources, whereas other parameters remained stable. Since females of several species prefer males with higher call rates, our results suggest that anthropogenically derived substrate-borne vibrations could reduce individual reproductive success. Our study demonstrates a clear negative effect of anthropogenic vibrations on anuran communication, and the urgent need for further investigation in this area.

“…It recognises that some sound exposures are at a level that no matter how long the exposure lasts it will never result in TTS (Ward et al, 1976). It is important to consider the effective quiet threshold when calculating sound exposure levels because accumulating low sound levels over long durations may result in an inflated impression of sound levels (Finneran and Branstetter, 2013). However, there is very little data on appropriate levels of effective quiet in marine mammals (Finneran, 2015).…”

“…Temporary threshold shift is determined by exposure frequency, duration, sound pressure level, temporal pattern of noise and available recovery time (Finneran and Branstetter, 2013;Finneran, 2015). Kastak and Schusterman (1999) found average threshold shift of 4.8 dB given exposure for 20 minutes at 100 Hz to sound pressure levels ranging from 133 -156 dB re 1µP a 2 .…”

“…In addition, mitigation measures to address any detected increase in underwater noise from shipping should consider the impact of sound pressure levels but also exposure duration and frequency given their ability to influence levels of TTS experienced by the seals (Finneran and Branstetter, 2013;Finneran, 2015;Joy et al, 2019).…”

“…24-hr sound exposure levels are often considered for regulatory assessments because the metric considers the duration of exposure as well as SPL and frequency (Finneran and Branstetter, 2013). The standard duration of exposure for non-impulsive sounds such as shipping noise has been 24 hours (National Marine Fisheries Service, 2018;Southall et al, 2007).…”

There is high spatial overlap between grey seals and shipping traffic, and their functional hearing range indicates they are sensitive to underwater noise emitted by ships. However, there is still very little data about the exposure of grey seals to shipping noise, constraining effective policy decisions. Particularly, there are few predictions that consider the at-sea movement of seals. Consequently, this study aimed to predict the exposure of adult grey seals and pups to shipping noise along their threedimensional movement track, and assess the influence of shipping characteristics on sound exposure levels. Using ship location data, a ship source model and the acoustic propagation model RAMSurf, this study estimated weighted 24-hr sound exposure levels (10-1000 Hz) (SEL w ). Median predicted 24-hr SEL w was 128 dB re 1µP a 2 s and 142 dB re 1µP a 2 s for the pups and adults respectively. The predicted exposure of seals to shipping noise did not exceed best evidence thresholds for temporary threshold shift. Exposure was mediated by the number of ships, ship source level, the distance between seals and ships, and the at-sea behaviour of the seals. The results can inform regulatory planning related to anthropogenic pressures on seal populations.a This paper is part of a special issue on The Effects of Noise on Aquatic Life.

Exposure of individual harbour seals (Phoca vitulina) and waters surrounding protected habitats to acoustic deterrent noise from aquaculture

1. Pinniped depredation at aquaculture sites is a globally recognized problem. To mitigate depredation, the aquaculture sector uses acoustic deterrent devices (ADDs) as a non-lethal alternative to shooting pinnipeds interacting with caged finfish. However, it is unclear whether sound emissions from ADDs have the potential to also impact non-target pinnipeds at spatial scales relevant to populations.2. Global Positioning System (GPS) tracking data from seven harbour seals tagged in a non-aquaculture context, on the west coast of Scotland, in 2017 were combined with modelled maps of ADD noise to quantify sound exposure and estimate the potential for auditory impairment. The acoustic model applied an energy flux approach across the main frequency range of ADDs (2-40 kHz).Predictions of temporary and permanent auditory threshold shifts were made using seal location data and published noise exposure criteria. The acoustic exposure of waters (10-km buffers) surrounding protected habitats (i.e. designated haul outs and Special Areas of Conservation (SACs)) on the west coast of Scotland was also assessed.3. All tagged seals and waters surrounding 51 of 56 protected sites were predicted to be exposed to ADD noise exceeding median ambient sound levels. Temporary auditory impairment was predicted to occur in one of the seven tagged harbour seals and across 1.7% of waters surrounding protected habitats over a 24-hour period, when assuming a 100% ADD duty cycle.4. Although the predicted risk of auditory impairment appears to be relatively low, these findings suggest that harbour seals inhabiting inshore waters off western Scotland are routinely exposed to ADD noise that exceeds median ambient sound levels. This chronic exposure risks negative consequences for individual harbour seals among the wider population in this region. The use of ADDs to mitigate pinniped depredation should be carefully considered to reduce unintended habitat-wide impacts on non-target species, including pinnipeds that are not specifically interacting with aquaculture.
