Something sounds fishy: mitigating noise aboard small industrial craft

I’d never before pondered that fish and noise might—even indirectly—have anything to do with each other. Little did I know! Sure, fish do tend to be quiet, but the process of harvesting them most assuredly does not.

With high casualty, accident, and injury rates, fish harvesting ranks as one of the world’s most dangerous industries. Occupational Health and Safety (OH&S) and Workers’ Compensation Board (WCB) literature from coastal communities not only confirms this; it also highlights noise-induced hearing loss (NIHL) as a primary health hazard among fish harvesters. What these regulatory bodies haven’t addressed is the noise-induced fatigue caused by insufficiently sound-attenuated crew quarters. Cumulative health effects of noise exposure over time also include cardiovascular stress, which can lead to high blood pressure and dizziness.

Let’s hear it for her too!

In Have you heard about her? Women’s innovative contributions to acoustics (Part I), we started off with a historical perspective, acknowledging Hedy Lamarr’s ground-breaking work in developing the frequency hopping spread spectrum, a technology still used in underwater acoustic communication and recognized as the foundation of WiFi, GPS and Bluetooth.

Have you heard about her?

Although Hedy Lamarr wasn’t an acoustician per sé, the frequency hopping spread spectrum technique she developed with avant-garde composer George Antheil was a milestone invention in the field of information technology, one still used in underwater acoustic communication owing to its anti-interference and anti-fading properties. These same properties explain why the two friends are widely credited with paving the way for later, more complex inventions including WiFi, GPS and Bluetooth.

Choosing an acoustical consultant: It’s all about due diligence

In crafting this opening paragraph, the most salient observation I’m inclined to share is that—just as anyone can call themselves a writer—anyone can call themselves an acoustical consultant. That doesn’t mean highly qualified acoustical consultants aren’t out there, but it does suggest you’ll need to take some time and care to find the right one for you. Hint: While anyone can indeed call themselves an acoustical consultant, acoustical engineers earn their titles through rigorous academic study and credentials.

6 reasons to hire acoustic consultants for your project … at an early stage in its progress

You trust your well-trained, compassionate family doctor. But would you be comfortable with a diagnostic hint of “It’s probably acid reflux, but it might be throat cancer”? Chances are, you’d be as unlikely to accept a “might be” as she would to let you leave her examining room before referring you to a specialist. At the very least, she’d send you off to a lab with blood test requisition in hand.
