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.
There’s not a lot to be said about last year that hasn’t been said ad nauseum, so I won’t waste your time or my own. And because we’re still bombarded with it when we watch the evening news, I’ll also refrain from using that C-word. (You know the one.) While most of us have cause for optimism as 2021 begins to unfold, here at BAP Acoustics we look back on 2020 with a considerable amount of gratitude. Good things happened… things that form a solid foundation for even better things to come.
Proposals were submitted. Proposals were won; enough so that we found ourselves growing the BAP team and consequently bringing that expansive energy to our clients’ projects. We couldn’t be more pleased about our recent additions, and we hope you’ll enjoy getting to know them as much as we have…
Whether you’re a parent, a teacher, or a student of any age, news headlines like the one above spell not only uncertainty, but an exponentially increasing likelihood that you may soon need to—if you haven’t already—set up a virtual classroom in your home.
If you’re familiar with our work and philosophy, you’ll know that we’re all about planning-stage noise mitigation measures vs/ so-called soundproofing… the latter almost worthy of MythBusters*. You’ll know BAP Acoustics gives no bandwidth to purveyors of noise-cancelling miracle materials and quick-fix solutions with no scientific basis. That said, there are ways—even in older homes—to enjoy noisy hobbies without inciting the wrath of your entire neighbourhood.
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.
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.
Ever wondered what acoustic engineering consultants are typically asked to do when they’re… consulted? Maybe you have an acoustics-related problem of your own but aren’t sure what questions to ask? First of all, please don’t hesitate to contact us and express your concerns, because at BAP Acoustics, we believe there are no wrong questions, especially not when they elicit sound advice. Secondly, we hear certain types of questions so frequently we feel they warrant their own blog post, so please read on. You may see your own question—or one relevant to it—addressed below.
Sure, noise can irritate even the most serene among us. But to label it an actual health hazard, like air pollution? That’s pretty hyperbolic, isn’t it? It’s only noise, after all; it’s not like it’ll kill us or something. Is it? Well, yes and no…
Oh wait, when someone deems noise to be a health hazard, they must be referring to the kind of high-decibel din found in some industrial workplaces, right? Jack hammers, chainsaws, welders… industrial machinery makes industrial noise; that’s why workers wear protective gear. Doesn’t adherence to OHS regulations ensure safety? Again, yes and no.
A few afternoons ago, gunshots woke me from an intentionally meditative state. Only they weren’t gunshots, as it took me a nanosecond to realize, but the sound of someone’s vehicle entering our building garage, driving over a tube-encased door control mechanism as it did so. I’ve lived here for several years now and the noise seldom bothers me, but it would if I lived over, below, or next to the garage. Fortunately, our building was designed and constructed such that no one does, and as a noise both air- and structure-borne, that unsettling bang-bang would be truly nightmarish if anyone did.
British Colombia is known nationally and beyond not only for its abundant natural beauty, but the real estate prices—the highest in Canada—that beauty inspires and enables. This holds particularly true for large urban centres such as Vancouver and Victoria, where owning a detached house remains out of reach for most middle class people. So it’s easy to understand how condominium (or strata) living presents a more accessible alternative. My husband and I live in the second Vancouver condo we’ve owned in the many years we’ve lived here and can attest to numerous advantages strata living offers, which, aside from relative affordability, include shared property maintenance costs and freedom from responsibilities like shovelling what little snow falls here.
