In a new genome-wide association study, an international team led by neuroscientists from Keck Medicine of the University of Southern California (USC) in Los Angeles has found evidence that some people may be more genetically susceptible to noise-induced hearing loss than others. According to an article in the April 16, 2015 edition of the journal PLOS Genetics, the study authors say that those found to be at higher genetic risk for hearing loss may decide to take additional precautionary measures to protect their hearing prior to noise exposure.
According to Keck Med USC, while gene association studies on noise-induced hearing loss in people have been conducted in the past, all were small and their results un-replicated.
In the Keck Med USC study, conducted at the Zilkha Neurogenetic Institute, Friedman’s team identified the Nox3 gene—almost exclusively expressed in the inner ear—as a key gene for susceptibility to noise-induced hearing loss. The study was conducted in collaboration with scientists from Brazil’s Federal University of Rio Grande do Sul, and UCLA. Prolonged exposure to loud noise—especially at higher volumes—can cause permanent hearing damage in a surprisingly short amount of time. Puro’s headphones tackle hearing protection in a two-fold manner: First, they create a tight seal around your ears. The second layer of protection comes into play when you connect the headphones to an audio source via Bluetooth.
The adult version, which open wider to accommodate larger heads, does not limit the volume.
It’s imperative to note that the LED indicator provides guidance as to how loud the music is at that particular point in a song.
For wireless connectivity, both headphones support Bluetooth 4.0 and will work up to 30 feet away.
To start my experiment, I took my Radio Shack SPL (sound pressure level) meter, calibrated it to 90dB, and put it directly against one of the ear cups. On the BT-5200, the results I got on my Radio Shack SPL correlated very closely with the indicator LED. For an on-ear—versus an over -the-ear—headphone, I was pleasantly surprised by the Puro’s ability to isolate outside noise. As for how they sound, I must admit to having—shall we say—reserved expectations given that Puro is marketing these products as headphones that will prevent noise-induced hearing loss. On some tracks, such as U2’s “Every Breaking Wave” and Sheryl Crow’s “My Favorite Mistake” and “It Don’t Hurt” from The Globe Sessions, the low-end dynamics were so good they sometimes came across as slightly accentuated. Speaking of Sheryl Crow, her vocals were beautifully set on a detailed soundstage and came across marvelously; however, I constantly felt they were not as full bodied and lacked the presence I’m used to through my (much more expensive) reference headphones. The Puro headphones have an uncanny ability to bring out fine details in just about every recording. Puro’s BT-2200 and BT-5200 wireless headphones don’t just protect your hearing, they look good and sound great.

Puroa€™s headphones tackle hearing protection in a two-fold manner: First, they create a tight seal around your ears. The model designed for adults (BT5200) won't prevent you from cranking the volume, but an LED will provide some guidance: When green, you're listening at a relatively non-harmful level. The second layer of protection comes into play when you connect the headphones to an audio source.

Correction:A This review was updated to report on the special cable that comes with the model BT-2200 that is designed for children.
By forming a tight seal over your ears to block ambient noise and warning you when you listen at too-high volume levels, these Bluetooth headphones can help protect you from noise-induced hearing loss. By forming a tight seal over your ears to block ambient noise and actively preventing the headphones from playing at at too-high volume, these Bluetooth headphones can help protect children from noise-induced hearing loss. Noise-induced hearing loss is the result of being exposed to excessively loud sound over a long period of time—such as working in a factory, using a chainsaw for hours, or riding a motorcycle or snowmobile, all without hearing protection. Hearing loss from noise exposure can be instantaneous, such as from gunshots, firecrackers and other impulse noises. An easy rule of thumb that can be used to assess whether the continuous noise in an area could potentially cause hearing loss is to determine if you have to raise your voice in order to be heard when speaking to someone three feet away. The most important thing to note is that noise-induced hearing loss is totally preventable!


If you are trying to protect your hearing from loud music, then consider custom Musician’s Earplugs.
Custom earplugs can also be made for dentists, flight attendants, pilots, bartenders, motor sports enthusiasts, DJs, band members, etc. If you believe you may be losing your hearing due to noise, regular audiometric testing can provide early detection. Remember that it is always better to hear with your own good hearing than to rely on hearing aids!
Noise-induced hearing loss is one of the most common work-related illnesses in the United States, according to the National Institute for Occupational Safety and Health (NIOSH), with troops in the Armed Forces being at especially high risk. Genome-wide association studies, or GWAS, search the entire genome for common genetic variants to see if any are associated with a trait.
Using 64 of the 100 strains of mice in the Hybrid Mouse Diversity Panel, the team was able to increase the statistical power of its investigation, leading to the first published GWAS for noise-induced hearing loss in mice. And while everyone’s hearing declines naturally with age, our lifestyle choices can be a key factor in noise-induced hearing loss.
Puro Sound Labs promises its Bluetooth headphones can reduce your risk of noise-induced hearing loss while listening to music. Instead, there is a tiny light just above the Bluetooth button on the left ear cup to indicate a safe volume level.
So, if the light is green when you start listening, there’s no guarantee that it will stay green if the song gets louder later on.
I found the volume buttons very easy to navigate by touch during use because of their shape and location on the ear cup. I set the volume on my iPhone and on the headphones to maximum and played several tracks from the Star Wars: The Force Awakens soundtrack. Playing the same tracks with the BT-2200 kids version, the SPL meter stayed at or below 85dB almost the entire time—only on a few peaks did it jump a few dB higher.
Depending on the content, there were times here and there where there was some extra sizzle, but that never took me away from satisfying listening sessions. And with price tags of just $80 for the kids edition and $130 for the adult, they deliver a price-to-performance ratio that’s tough to beat.

Turn down the volume when listening to music if possible, especially if you are using an iPod or other similar device via earbuds. Traditional hearing protection typically decreases higher frequency sounds disproportionately. Why go through all the effort to wear hearing protection when it does not provide adequate attenuation? If your hearing continues to decrease, you are in a great position to take more aggressive steps to prevent additional loss.
In 2013, the Department of Veterans Affairs reported hearing loss as one of the most common disabilities among veterans receiving disability compensation. Mouse GWAS have led to the discovery of hundreds of genes involved in complex traits that have immediate relevance to people, say the study authors. The study authors say that more research is necessary before clinical recommendations can be made. According to the National Institute on Deafness and Other Communication Disorders, as many as 16 percent of teens (children aged 12 to 19) have reported some hearing loss that could have been caused by loud noise—including listening to music while wearing headphones. The company sent its model BT-2200 (for kids) and model BT-5200 (for adults) for this evaluation.
The kid-oriented BT-2200 headphones, which look identical to the BT-5200 model aimed at grown-ups, will limit the volume to a maximum of 85dB. Puro gives the following guidance for the BT-5200: Green means that the volume is less than 85dB. And if you connect either model via the 3.5mm cable, instead of Bluetooth, all bets are off. In case you’re wondering, the USB input cannot be used as a digital audio connection between a laptop and the headphones.
The Bluetooth button also functions as a pause button while you listen to music, and you can use it to answer and terminate calls when paired to your smartphone.
Puro claims a fully charged battery will deliver about 24 hours of battery life and a jaw-dropping 260 hours of standby time.
But when I switched from Bluetooth to a wired connection, the SPL’s needle spiked up to 94dB or more at some musical peaks.


Taking the Puro headphones for a spin on an east-coast train significantly reduced and muffled—but obviously didn’t eliminate—the noise around me. The Puro BT-5200 and BT-2200 sound superb, delivering an extremely pleasing, well-balanced presentation. Drums on the track, “Main Title and Attack on the Jaku Village” were dynamic, carrying both weight and definition.

Such hearing loss is insidious, gradually robbing the exposed person of high frequency sounds, such as the s, th, ch.
Have some type of hearing protection easily available in your garage when you are picking up that weed-whacker or hopping onto your riding lawnmower.
When deciding between the various pre-packaged hearing protection, look for an NRR (Noise Reduction Rating) value or ask your audiologist. If there’s too much noise around you, you’ll feel the need to make the volume louder and louder to hear your music.
You can blow past the 85dB threshold on the kids model, and the warning indicator on the adult model will not light up.
Puro uses custom-made 40mm drivers, although the material they’re fabricated from wasn’t disclosed.
Double-pressing the Vol + button advances to the next track, while double-pressing Vol – takes you to the previous track. If the battery runs out, you can still use them as traditional wired headphones, though as I mentioned above, you lose the hearing-protection features when you connect in this way.
In various contexts at home and on the road, I found that the Puro delivered on this count. You could feel and discern the decay of the drum’s membrane instead of it just flopping into a muddy mess. If therea€™s too much noise around you, youa€™ll feel the need to make the volume louder and louder to hear your music.

You could feel and discern the decay of the druma€™s membrane instead of it just flopping into a muddy mess. So it becomes difficult to differentiate “ace” from “eight” and “fifty-six” from “sixty-six.” Women’s and children’s voices will also be more difficult to understand. Put spare earplugs in the glove box of your car and bring them into the movie theater or to that concert you are attending. The higher the number, typically the better the effectiveness, assuming the earplugs fit well and are used appropriately. Musician’s earplugs have a filter that reduces the sound equally across the frequency range.
The kids version come with a special that will attenuate the volume so that it doesn't exceed 85dB. Kids won’t feel like they are getting a second-class, dumbed-down product because the two versions are very nearly the same. The inside top of the case is outfitted with a netted pocket to hold headphone accessories.
