When talking about sample rates it gets more complicated than 44.1k being ok for anything below 22.05kHz. The difficulty arises in the recording stage before the A/D conversion. Frequencies above half x the sampling frequency have to be completely filtered out with analogue filters, otherwise...

I got my Beyer DT880 last week, and from all the descriptions I've read it would seem that equalizers haven't been invented yet. By producing an EQ curve that is an upside down version of the Headroom measurements, I've greatly improved their sound. It has eliminated the treble peak that causes...

I'm pleased,... but also a bit disappointed I received a new pair of Sennheiser PXC 250 noise cancelling headphones just the other day, and while I'm mostly happy with them, I'm hugely disappointed with one aspect, and that is the noise cancellation at low frequencies. It doesn't compare well...

I've had 2 pairs of noise cancelling headphones, and although I think they work, these things are not for everyone. I've found that not everyone hears low frequency droning and background rumbles in the same way. On a noisy ferry for example, without noise cancelling headphones I find it...

I was actually looking at those "in-ear" electrostatics earlier. Do they block the ears like the Etys and Shures? My ears are pretty sensitive to DC pressure changes, so I wouldn't be able to live with that sort of thing unfortunately.

Thanks people . Where would it be possible to see measurements of far-field sounds as heard by a dummyhead, especially of sounds above 1kHz? This could probably be done with a high quality tweeter EQ'd with DSP, and played at a sufficient distance from the dummyhead to ensure that resonances are...

I'm looking for a pair of headphones that will sound pleasant and non-fatiguing, especially in the midrange frequencies. I've DIYed a couple of loudspeakers, so I'm looking for info from a slightly different technical perspective. For me some of the most useful information that speaker...
