Each speaker driver is carefully hand picked, tuned and tested before being paired to ensure the most balanced natural sound. The Fidelio NC-1’s lightweight, slim and compact foldable construction in a stylish design makes it the perfect travel companion. The noise cancellation feature of the Fidelio NC-1 is specially tuned with optimal sound performance in mind.
With the in-line control and mic, you can easily switch between your music and phone calls. The Fidelio NC-1’s standalone acoustic chamber ensures that sound is not affected by its components for active noise cancellation.
Fidelio NC-1 uses a feed-forward and feed-backward active noise cancellation (ANC) solution, which means there are 4 microphones implemented inside and outside the ear cans to capture noise for advanced processing. By signing-up, you agree that EXPANSYS PLC and their respective group of companies can contact you from time to time by email, phone, post, SMS or MMS with information on products, services and offers. Bonus: Although this technology is a sham for headphones, it’s being tested on a larger, 3-dimensional scale to reduce the noise of aircraft in communities near airports! Jacob has a degree in Aerospace Engineering from Embry Riddle Aeronautical University, and now works for a major defense contractor in sunny Florida, as an aircraft structural analyst.
Actually, speaking of earplugs, the latest thing for earbud headphone design seems to be silicone earplugs with holes to admit sound from the headphone speakers. My fiancee can’t stand those kind of earplugs, and I can’t wear them at work because I need to hear when someone sneaks up on me, but I have worn them on an airplane before and they worked pretty well!
I’ve been using the Shure passive noise-cancelling headphones for years, and love them. If there was a deafening sound source, what would happen if you had a speaker cancelling it?
Since sound energy is just the kinetic movement of air (caused by pressure differentials), if an equal and opposite movement of air encounters the incoming sound, the kinetic energy of each source is completely canceled by the other.
And yes, due to the spherical propagation of sound waves, you would need a lot of speakers around an airport in order to make it work. I have devised a new way of music listening for audiophiles based on a physiological principle I have discovered and applied to music listening. The technique I have discovered is simply to open your mouth as wide as you can while listening to select passages of beauty and voila!, all instruments show an uncanny presence, rarely heard otherwise. Later I tried it out of curiosity while listening to music with a marked improvement of the listening experience.


From now on and more than ever, dedicated audiophiles will be easy to spot practicing their art among the regular crowd at audiophile trade shows or at your local audio salon. In a circumstance parallel to yours a yawn and stretch while wearing protective earphones in my workshop the other day brought me a burst of sound which, just anecdotally, did seem very bright and spatially rich. If you think that you have a hearing loss and would like to talk about it with an experienced audiologist, please make an appointment for a full hearing assessment. There is no obligation to buy and you will have the opportunity to discuss your concerns, learn the exact nature of your loss and consider possible solutions. The following list of questions, while not exhaustive, will provide good indication of any hearing problems. If you have answered 'yes' to three or more of these questions, we recommend an in-depth hearing assessment with one of our hearing aid audiologists. These ear muffs feature cutting-edge noise reduction technology that blocks out only the sounds that exceed safety levels. The 40mm drivers utilize high power neodymium magnets to deliver true high definition sound in a wide dynamic range, right down to the most minute details. With multiple ways of folding the headphones, you can decide how the headphones can fit efficiently in your travel bag or even in the pocket of airline seats.
Challenging the perception that noise cancelling headphones cannot deliver high performance sound, the NC-1 is engineered to deliver the best audio quality whether you’re in a quiet or noisy environment. Fidelio’s superb noise cancellation lets you enjoy crystal clear calls even in bustling environments. Every natural sound detail is isolated and precise, dynamic bass is intact – without any compromising on sound clarity. The feed-forward ANC (mic outside the ear can) covers a wider bandwidth of frequencies, while the feed-backward ANC (mic inside the ear can) provides fortified noise cancellation.
Not at all.  Earplugs can literally be bought with the change in your pocket, and do a much better job of creating silence for your ear-holes. Loudspeakers are set up around the airport that play the off-phase sound waves for the engine noises, and word-on-the-aerospace-street is that, after a lot of optimization, it works really well! They work really well, and the darn things only cost $20-30 for the top-of-the-line brands. I noticed that whenever I opened my mouth ever so slightly, the street’s hustle and bustle I heard in my head increased noticeably, much to my surprise. While I can’t quantify the improved quality of listening the idea that the stretch opens additional passages to the ears seems solid.
We even offer trial periods on some of our hearing aids, so you can discover just how much you may have been missing out on. Other causes include hereditary factors, prolonged exposure to noise exceeding 85 decibels (the equivalent to heavy road traffic), illness, accidents or even some medications.


A proper hearing test will determine the nature of your loss, whether you require further medical opinion and whether a hearing aid can help.
It will only take a few minutes and will test how clearly you can hear in different levels of background noise. There is no substitute for a proper hearing test carried out by a trained hearing aid audiologist.
Featuring over 200 hours of battery life on two AA batteries (sold separately), hands-free operation and an LED indicator light, these ear muffs offer user-friendly noise reduction ideal for the workplace or garage. Compact foldability and long-wearing comfort make it the best sound companion on long haul or daily commutes. This combination ensures cancellation over a wide frequency range and to a deeper extent for optimized music enjoyment in any environment. You can even get earbuds that have memory foam earpieces that fit the shape of your ear canal exactly to block out external sounds.
Normally the Eustachian (or auditory) tube is closed, but it can open to let a small amount of air through to equalize the pressure between the middle ear and the atmosphere. One of the techniques pilots use to relieve occasional painful pressure blockage in the ears is essentially the same. The majority of hearing loss is ‘sensorineural’, namely irreversible damage to the sound-conducting hair cells of the inner ear. One can open it voluntarily by swallowing or by opening one’s mouth wide open (useful in elevators).
Perhaps your dentist could make a special mouthpiece for listening purpose, if you don’t mind looking like a cartoon crododile with a stick in its mouth (audiophiles have been known to do much worse, like elevating audio cables 2 inches from the floor).
The degree of loss can range from mild to profound, and most people with hearing difficulties can benefit from using hearing instruments.
Continuing to suffer with hearing loss can significantly affect our social life and our relationships, and often leads to a feeling of isolation.
The only annoying downside is that your mouth has to be really very wide open as in a locked position (a bit like the famed MGM lion of old), which is quite uncomfortable if held too long. You can hear conversations around you during low noise and the sound is about cut off during high noise. They won't hold up to man handling like some more expensive ones but I can go through 4 pairs of these before the price even compares !!
