Is there a reason they require device specific tests? It's the "unknowns" not accounted for in the models that are the (potential) issue. If you have time read through this Ars Technica thread where a bunch of these questions are hashed o

I'm sure they'd be happy to leave with an extra bonus of a tablet after that. How well does a tablet perform when its screen is caked in concrete? Repeating part of a comment I made a few days ago: Folks have been talking about tablets be

Cheap tablets will dominate the market, Mr. Moore will make sure of it. And much like in the music player market, I suspect the bulk of those cheap tablets will have an Apple logo on it. You do realize that Apple will also get to benefit

The unobvious but major thing missed is that hiring the wrong lawyer is far more expensive than an additional $300 per hour You could say the same for any number of industries - hire the wrong structural engineer and that bridge or buildi

No, Holosonics is not creating sound from beating, they are using heterodyning, which takes advantage of how high-amplitude ultrasonic sound waves interact with the atmosphere, that's different from beating.

This: Yes, but the effects of interference patterns between multiple ultrasonic frequencies is the same, and definitely does affect the audible spectrum has nothing to do with this: This is why we must filter the square wave that comes o

That article describes hetrodyning which happens because ultrasonic frequencies at high amplitudes interacts nonlinearly with air. You are not going to see that effect with sound waves generated near the audible spectrum, and normal loudspe

No, even in that case, the room can still overpower the speaker. A $200 HTIB system in a properly treated room will sound a lot better than $28,000 Wilson Watt Puppies in a bathroom for example.

Agree one-hundred percent about the room (although the prescription isn't always as simple as "get a thicker rug" etc). The other issue regarding high-frequency sound reproduction is that in most cases, the loudspeaker won't be outputting m

Harmonics in real-world instruments are not usually exact multiples of the fundamental. A simple diffeq model of a rigid oscillator will show you this mathematically. That is absolutely incorrect, mathematically speaking, harmonics are b

If you're not going to hear the frequency, then there's no reason to record it, so I don't see what you're objection is.

44100 is not a bad sampling rate, but it necessitates very sharp aliasing filters, When you're talking about recording , sure, but in terms of storage and playback, we solved that problem 20 years ago with oversampling.

For example, the human hear will hear a 30kHz frequency if it's fundamental is 10kHz You are going to have to provide me with a citation to back that up because that goes against everything I've learned and experience in 17 years of worki

in the US, many MRI places are 9-6 A nit, but is this actually true? I've had 7 MRI's (5 health-related, 2 research-related) and only one of them was during business hours. I've had MRIs done at 9pm, 11pm, 1am, 4:30am, 6am etc.

This isn't a new idea, it's just a "portable" version of the anti-vulgar-speech system you see at many sporting stadiums that play back delayed recordings of crowd noise when vulgar chants (i.e. "bullshit! bullshit!" after a bad call) start

Bone conduction only works well for lower frequencies, unless a transducer or vibrating object is directly coupled to your body. Earplugs would work just fine in this application.
