Whales talking on new frequency due to ocean noise

Avery Thompson, Popular Mechanics, reports that “[n]ew research suggests that blue whales are changing their communication band due to noise from human ships.” Thompson writes that noise from ocean liners and large container ships can travel for miles below the waves, disturbing animals like whales and dolphins. Researchers from from Oregon State University are finding that blue whales are learning to adapt to the noise by changing the frequency with which they communicate, and they “believe that the whales are doing this deliberately to avoid interference from human sounds.” Of course, the scientists aren’t completely sure, but as shipping companies move to using quieter electric ships, they will be able to see if the whales go back to their former frequencies.

And it’s not just whales and dolphins that are reacting to ocean noise. Researchers at Newcastle University have discovered that “European sea bass experienced higher stress levels when exposed to the types of piling and drilling sounds made during the construction of offshore structures.”

It’s long past time that humans start considering the harmful effects our noisy existences are having on each other and every other living thing on this planet.

 

Does the sound of chewing or pen clicking make you enraged?

You are not alone.  Misophonia is a disorder marked by “a hatred of sounds such as eating, chewing or repeated pen clicking.”  It’s not well understood, but the known universe just got a lot bigger thanks to a team of researchers from Newcastle University who have evidence that enraging noises are caused by a brain connection overdrive.

The lead researcher, Dr Sukhbinder Kumar of the Institute of Neuroscience at Newcastle University and the Wellcome Centre for NeuroImaging at University College London, said that, “[f]or many people with misophonia, this will come as welcome news as for the first time we have demonstrated a difference in brain structure and function in sufferers.”   With this news suffers may see the end of one problem they often face; namely, the casual dismissal of their complaints by medical professionals.  As Dr. Kumar notes, “[t]his study demonstrates the critical brain changes as further evidence to convince a sceptical medical community that this is a genuine disorder.”
