The Truth About Noise

Anemic? See your doctor and get your iron tablets, stat:

Iron Deficiency Anemia Tied to Hearing Loss.  Iron deficiency anemia should be relatively easy to manage. So see your doctor, get a blood test, and manage your anemia.

That said, Dr. Daniel Fink, a leading noise activist, cautions that the study appears to be a preliminary one. The study reviewed data from approximately 300,000 deidentified adult patient records at Milton K. Hershey Medical Center in Harrisburg, Pennsylvania. The diagnosis of hearing loss was made by mention of one or more diagnostic codes for hearing loss on at least one encounter. The diagnosis of iron deficiency anemia was made from laboratory tests. Then statistical analyses were performed. No audiometric tests were done, and the prevalence of hearing loss was much lower than that reported in other studies.  Dr. Fink thinks this report might help guide future research, but the fact remains that noise exposure, not iron deficiency anemia, is the major cause of hearing loss in the United States.

Looking for a free professional grade sound level meter app?

Look no further: Introducing the new NIOSH Sound Level Meter App. Yes, the National Institute of Occupational Safety and Health (NIOSH) has just released a free sound level meter app for IOS (Apple) devices. Recognizing that “most of the apps on the market are oriented at the casual user and lack the accuracy and functionality necessary to conduct occupational noise measurements, NIOSH hearing loss researchers collaborated with an app developer, EA LAB, to create an iOS based sound level meter app that measures and characterizes occupational noise exposure similar to professional instruments.”

NIOSH has developed this app so that “workers around the world [can] collect and share workplace (or task-based) noise exposure data using their smartphones.” And once the data has been collected, “[s]cientists and occupational safety and health professionals could rely on such shared data to build job exposure databases and promote better hearing health and prevention efforts.”

NIOSH is making the app available to anyone who would like to download it. Click here to learn more about the app and for the link to download it at the App Store. NIOSH is looking for any and all feedback about the app and asks that you help them spread the word about this new tool for protecting workers’ hearing.

We know the feeling:

In “Why I hate my fellow commuters in the quiet carriage.” Brian Yatman, The Sidney Morning Herald, writes about commuting by train and how the quiet car is abused by the rude and ignorant.  We’ve been there, although unlike Mr. Yatman we may have asked someone to keep it down once (or three times).  In any event, his suggestion for maintaining quiet car decorum is spot on:

What we need is some kind of official presence authorised to apply the shushing finger of the law. These marshals would glide about in comfy shoes, separating chatty couples, handing out Reader’s Digests, keeping the peace. They would issue warnings in the form of aphorisms. “Let us be silent, that we may hear the whispers of the gods,” they would intone, invoking the words of Ralph Waldo Emerson. Repeat offenders would be escorted off the train.

Or offenders could be thrown off, literally, to save time (and quickly escape the sound of their screams).  Do not violate the sanctity of the quiet car.

As if air and water pollution weren’t enough:

Noise pollution from fracking may harm human health.  Brett Israel, UC Berkeley News, writes that “[f]racking creates noise at levels high enough to harm the health of people living nearby, according to the first peer-reviewed study to analyze the potential public health impacts of ambient noise related to fracking.”  What kind of health impacts?  The researchers found that “noise from fracking operations may contribute to adverse health outcomes in three categories, including anxiety, sleep disturbance and cardiovascular disease or other conditions that are negatively impacted by stress.”  One more reason to end fracking.  Click the link for a detailed description of the “complex symphony of noise types” associated with fracking activity.

We can’t tell if this is an elaborate joke (or not):

Hushme’s voice-masking headset could save your sanity! Or not.

The 2017 Consumer Electronics Show in Las Vegas just wrapped up and, as usual, there were a handful of “interesting” gadgets that we may or may not ever see online, much less at a retail store.  Hushme must be on that short list.  Essentially, Hushme is a mask you place over your mouth (while wearing Bluetooth earbuds) that allows you to take a phone call without other people hearing you.  And to add an element of fun to this “interesting” product, the manufacturers allow you to play a series of sounds through external speakers to further obscure things (while killing the idea that Hushme will allow you to make a call without distracting those around you, but whatever).  How is playing sound through external speakers fun?  When it’s “sounds of some R2-D2-style beeping” or “[h]eavy, Darth Vader-ish breathing.”  Fun!

Click this link to view the Hushme promotional video and see if you agree with the description of the Hushme as “stylish.”  And be sure to keep your eye out for Hushme’s crowdfunding effort scheduled for sometime this year.  $200.  That’s what they expect to ask for each and every Hushme.

A little self-help can’t hurt

In light of the recent study linking traffic noise to an increased risk of acquiring dementia, this article is a must read: How To Reduce Noise Pollution At Home.

Of course, one would hope that governments would think about how best to limit noise after reading that frightening study.  The medical costs alone should be enough to motivate even the most dispassionate bean counter.  But until they do, we really must take matters into our own hands and try to make our homes as peaceful and noise free as possible.

God save us from the sound branders

Imagine all of this “sound branded.”

Because there isn’t enough noise in the world. Goldstein, a “music and sound consultancy with an outstanding track record in film, advertising, experiential marketing and sound branding,” writes about sound branding.  What is sound branding, you ask?  Goldstein explains:

There is a common misconception that the term Sound Branding refers only to the creation of ‘sonic logos’ or ‘sound signatures’. While these elements undoubtedly played a significant part in developing the field, it has expanded into something much richer and more valuable than a synonym for jingle-making. In its totality, it’s about the strategic curation of anything that can be usefully heard by a target audience – this could be a bespoke composition for an interactive product, the playlisting for a chain of hotels, or even an installation of generative sound art for a department store.

We would suggest a simpler–and more accurate–definition: the purposeful intrusion into an individual’s’ personal soundscape by someone trying to sell them something.  Adding that the idea of companies competing by employing sound branding could quickly spiral into hell on earth in public spaces.

Age doesn’t matter,

you could have hidden hearing loss (and not know it). WMAR Baltimore reports on hidden hearing loss, a relatively recently discovered hearing breakthrough that explains how people who pass hearing tests have problems hearing in noisy environments.  WMAR interviewed audiologists about this breakthrough, who said that “why patients can’t decipher speech in noisy situations has been unexplained, but a new breakthrough is changing that.”  The researchers who made the hidden hearing loss breakthrough studied young adults who were regularly overexposed to loud sounds, and found that “hidden hearing loss is associated with a deep disorder in the auditory system.”

It’s never too late to protect the hearing you have.  Exposure to loud sounds damages hearing.  Period.
