Seismic airguns can produce sounds exceeding 230 decibels underwater at the source.
Seismic surveys used in offshore oil and gas exploration generate intense low-frequency sound pulses. These pulses can overlap with the 15 to 30 hertz communication range of fin whales. Studies published in Marine Pollution Bulletin have documented acoustic masking effects in baleen whale habitats. Fin whales rely on long-distance low-frequency calls for social communication and possibly mating coordination. When seismic noise increases ambient sound levels, signal transmission range may be reduced. Research vessels deploy hydrophones to measure overlap intensity. Regulatory bodies now require environmental impact assessments before large-scale surveys. Industrial sound alters acoustic landscapes beyond visible disturbance. The ocean carries noise farther than expected.

Acoustic overlap research informs government permitting decisions for offshore energy projects. Agencies such as NOAA integrate sound propagation modeling into environmental reviews. Mitigation strategies include seasonal restrictions and exclusion zones. Institutional collaboration between energy firms and marine biologists has expanded monitoring programs. Noise pollution joins ship strikes and entanglement as modern anthropogenic pressures. Policy evolves as measurement improves. Science translates frequency into regulation.
For the public, the idea that unseen sound can disrupt unseen giants adds complexity to industrial expansion debates. The whale’s call competes with mechanical pulses. Communication becomes vulnerable without physical contact. The sea amplifies both biology and industry. Conflict occurs in invisible wavelengths. Impact can be auditory rather than visual. Silence is no longer guaranteed.
