isolating

During my recent vacation, I rediscovered the importance of owning good headphones. Specifically, noise-isolating earbud 'phones, the kind that allow you to watch a movie on an airplane, listen to music in a noisy coffee shop, and go for a run without wind noise drowning out your tunes.

Alas, my earbuds are always going missing--or getting permanently "borrowed" by certain family members who shall remain nameless (all of them). That's why when I see a deal, I like to stock up.

While supplies last, J&R has the Altec Lansing Muzx Core MZX206 noise-isolating stereo headset for $12.99, … Read more

I live in New York, N.Y., a place that's never quiet. It's not just traffic noise, people noise, music in the streets, or the cumulative effect of all the buildings' air conditioning exhaust fans. There's a low, deep hum that always throbs to the beat of a city of 8 million people.

Judging by the number of folks wearing headphones on the subway, I'm not the only one using music to mask the noise. The subway may be one of the loudest places you can be in this town, but restaurants can get painfully loud, … Read more

When it comes to fantasy shows on HBO right now, I'm more of a "Game of Thrones" kind of guy, but I've been hearing a lot of chatter about the new season of "True Blood" as well. As V-Moda continues to offer more personalized headphones, the company's latest addition to the lineup is a partnership with HBO to bring "True Blood" fans a special-edition V-80 on-ear headphone.

The hardware features dual "ear shield" covers that pop off and allow the user to customize the design to go along with favorite images from the show, including a night club, Fagtasia, and the Japanese symbols you see on the "Tru Blood" beverage. V-Moda goes a step further and even lets you choose your own blood type to laser etch onto the earpiece, bringing you that much closer to the action.

In terms of the headphones themselves, the V-80 model is V-Moda's lightweight mobile headphone that features dual 40mm drivers and an extra bass push without the hassle of popping in extra batteries (looking at you, Monster). Other accolades for the V-80 include a Kevlar-wrapped cable, integrated remote control and microphone, and a "True Blood" exclusive "exoskeleton" protective case with a blood vial zipper.

The True Blood V-80 headphones are available now at the HBO online store and other online retailers for $230.

I occasionally receive e-mails from readers worried about loud music's potential for damaging their hearing. The concerns are very real; a recent study found that one in five adolescents now suffers some hearing impairment. How loud is too loud? If you regularly experience "ringing" in the ears, see your doctor!

Cranking the volume of your headphones up loud will (eventually) deafen you, unless you're using the new dB Logic headphones ($40). They use SPL2 technology to automatically limit the maximum volume to a safe level. Sure, there have been other headphones that promised to do the … Read more

The holiday season is a peak time for traveling, as many people gear up to take advantage of the kids' time off and visit family and friends. If you're traveling by air this year, a high-tech travel bag can help you ward off tedium and the annoyances that come with being contained on an airplane with dozens of strangers.

My main goal when flying is to drown out crying babies, obnoxious passengers, and droning engines, so the first thing that goes in my carry-on is an MP3 player--but it's not much good if I can't hear the … Read more

It's a noisy world and getting noisier all the time. No wonder sales of noise-canceling and noise-isolating headphones are booming.

Dwight Garner's New York Times article, "Meditations on Noise" reports on three books covering the impact of sound and noise on our lives.

Noise is usually classified as unwanted sound, but one person's noise is another's bliss. I've always been fascinated by electric guitar distortion, which can sound beautiful. Musicians such as Link Wray, Jimi Hendrix, Neil Young, and Jonny Greenwood mastered the art of noise. Why humans like such unnatural sound is a mystery to me, but it appeals on a primitive, strangely organic level. That, or it's noise, ugly, nerve-wracking, unwanted sound. Indulging in loud music can be risky business; if you occasionally experience "ringing in the ears" after exposure to loud sounds or concerts, you may be losing your hearing.

Garner looks at three books: Garret Keizer's "The Unwanted Sound of Everything We Want: A Book About Noise" (PublicAffairs); "Zero Decibels: The Quest for Absolute Silence" (Scribner), by George Michelsen Foy; and "In Pursuit of Silence: Listening for Meaning in a World of Noise" (Doubleday), by George Prochnik.

I never thought about it until I read the article, but noise exposure has social and political aspects. Garner put it this way: "You can judge a person's clout--his or her social and political standing--by witnessing how much racket he or she must regularly endure." Right, money can buy whatever degree of solitude you need.

Technology may be the source of much of the aural bombardment, but it also offers remedies. We can block out some of the din with our iPods and such, but using music to mask noise can be dangerous. When earbuds and other headphones don't hush outside noise you have to turn up the volume louder than the noise to hear the tunes, so you're compounding the problem. That's why noise-canceling and noise-isolating headphones are such a good idea; they let you turn the volume down and still hear more of the music.

Reducing background noise, in and of itself, lets you hear more deeply into the music. It's not a small, audiophiles-only distinction. Noise masks the subtle stuff, so you can't hear the reverberation surrounding a singer's vocal, or the gentle strum of an acoustic guitar. When the background noise level is high you only hear the louder sounds in the music. Listening "through" noise is stressful and fatiguing; mute the noise and you hear more and feel better. … Read more

In a world where teens are more likely than ever to be staring at a display, a new analysis has found that all that screen time may be linked to detachment.

The researchers, who examined a 2004 study of more 3,000 youths aged 14 and 15, found that those who spent more time in front of television or computer screens also had more difficulty engaging in a rewarding relationship with parents. In fact, the possibility of low attachment between the teens and their parents increased by 4 percent for every hour of TV screen time, which could include gaming. … Read more

I occasionally get e-mails asking about cheap and easy ways to soundproof a listening room. Readers want to minimize the amount of bass and sound leaking into neighboring apartments or rooms in a house from their home theater.

Bona-fide soundproofing is neither cheap or easy. Anything short of building a "floating" (isolated) recording studio type listening room won't totally soundproof a room. You see, a floating room's ceiling, walls, and floor are acoustically and structurally isolated from its surroundings. Prices vary, but plan on investing at least $10,000 for a professionally installed floating room. After the floating room construction techniques, you can attain more limited success with double sheetrock on the walls. That is, install new double sheetrock walls with an air gap between them and the original walls. Double sheetrock can make a big difference, but it's still far from a cheap or easy solution.

A friend put a layer of lead sheeting under his apartment's finished wood floors to reduce bass transmission to the floor below. It worked, but I'm not so sure about the health concerns from living around that much lead.

But I do have a few tips to reduce sound leakage from one room to another, or between floors of a house or apartment that won't break the bank.

Before we go any further, let's define our goals: sound isolation isn't the same thing as improving room acoustics (I'll cover that in another blog).

Sound is transmitted from one room to another either through structure borne vibrations (wall, ceiling, or floor movement), or through the air. Thick carpets or wall pads won't do much in the way of soundproofing, but they may improve sound quality in the room.… Read more

It seems like every Tom, Dick, and Harry is putting out headphones these days, and far be it for Radio Shack to be left out in the cold. The electronics retailer is turning out a line of earphones sporting the brand name Auvio.

The line includes a handful of models that range from the very cheap ($15) to the top-of-the-line In-Ear Armature headphones featured here. This set goes for a still-affordable $80, though it's practically impossible to recommend them over the comparatively priced Klipsch Image S4. The Auvio In-Ear headphones just don't stack up in terms of sound … Read more
