Based on available information, making loud noise can potentially scare a killer whale (orca).
Using Noise to Deter Orcas
Boaters interacting with orcas have reported success in deterring them by creating significant noise. This tactic has been employed in situations where orcas have been closely approaching or interacting with vessels.
Effective Noise Types Mentioned:
- Fog Horns: One report specifically highlighted that the sound of a fog horn was particularly effective in causing orcas to move away.
- Firecrackers: Cruisers have also reported using firecrackers as a method to scare the whales.
- Banging on Boats: Creating loud sounds by banging on the hull or other parts of the boat is another reported tactic.
These instances suggest that sudden or loud auditory stimuli can be disruptive and potentially deterring for killer whales in certain contexts.
