New@NAMM: The Earplug Redefined

DUBS Acoustic Filters are stylish, high-design earplugs that utilize advanced acoustical physics to reinvent hearing protection. By leveraging the way the ear processes sound, the DUBS accomplish two goals simultaneously: lowering sound by roughly 12 dB, and preserving audio fidelity. With the DUBS, every participant in the music industry – including DJs, musicians, sound mixers, producers, roadies, security and fans – can hear with crystal clarity while minimizing the damaging impact of high-decibel noise.

How They Work

For DUBS Acoustic Filters, Doppler Labs developed a proprietary technology that effectively leveraged the way the ear’s sensitivity to sound changes in response to different decibel levels. DUBS Acoustic Filters use both a “low pass path” and a “high pass path” for audio. As sound makes its way through the low pass via two of the DUBS chambers, the sound enters a small, final diameter tube where it exits inside the ear. The large expansion areas cut off high frequencies, so users only hear lower frequencies through this combination.

The high pass path consists of a single small diameter tube, connecting the outside world to the user’s ear. As sound enters the tube, low frequency sounds are “bled off” by a controlled leak, and high frequency sounds continue through to the ear. The result is a controlled acoustic experience that produces a distinct audio curve, which is quite unlike anything in the earplug space, which has traditionally offered low-tech foam inserts.

The DUBS Acoustic Filters were developed to be as much a sleek accessory as a hearing protection device – aesthetics and acoustics are both primary concerns for Doppler Labs. The DUBS now come in four colors: teal, blue, pink and white. They are available for $25 through and at Best Buy and Amazon, as well as in select European countries, including the UK, with new countries to be added in Q1 2015.

About the author

Tim Hemingway

I want to be a rockstar when I grow up, at least that is what I have been putting down as my career goal ever since I was first introduced to the Beatles at 11 or 12 years old. Shortly after my introduction to the Fab Four, I picked up an old classical guitar and started learning every Beatles song I could. It was right around that time that the nickname "GuitarGuy" Tim originated. While I don't remember the exact origin, it was basically how kids at school differentiated me from the other 4 or 5 Tims in our class. Starting in Jr. High, with an arsenal of Weezer and Green Day covers, my friends and I began "performing". Over the next 10 years I played guitar or bass in various alternative, punk and acoustic bands. Somewhere mid-way through college I realized that although I had the desire to be a rockstar, maybe I didn't have the songwriting abilities, so I moved my passion for music behind the console. I then spent several years working in a studio by day, and at night running everything from local concerts to community musicals. Without all of the boring details, my studio work eventually led me into advertising and marketing which is what I now do during the day. But when I come home at night, I still pull out my guitar and put on concerts for my kiddos (I’m raising up the next generation of Guitar Gods). I met up with the Rev while I was in grad school and was working on my thesis: Turn it up to Eleven: A Study of Guitar Hero and Rockband gamers. Why they play and how marketers can use this information. Yes, it is true. I have several academic publications about Guitar Hero. At that time in my life I had decided to pursue a career in marketing within the music industry, but the Rev had a better idea. He gave me a shot at reviewing gear, and ever since then I have been a regular here as part of the Live2playNetwork dysfunctional-family. When it comes to music, I'm a jack of all trades. While I'm not an expert at anything, in a pinch I can play guitar, bass, drums, sing, or I can mic up the drum kit, edit in Pro Tools, or solder up a new patch cable.
