Several acoustic absorbers with different shape and size were made for the new Room 2 listening room.
Why Vinyl Sounds Better
Vinyl sounds better, right? If so, there is a reason that can be explained in technical terms. Let us find out.
The answer is simply that vinyl does not sound better, in fact it is inferior to digital.
Testing Amplifier Sound Quality
This is something I have though about a long time now – finding a method to reliably verify sound quality differences in power amplifiers.
Finally I have set up the necessary instrumentation to try out the method in practical experiments.
Audibility of peak limiting
Audibility of phase distortion
Phase distortion at low frequencies causes audible degradation of music.
When is it audible, what causes it and how does it affect sound quality.
Floor reflection fixed
Floor reflection fixed with two small additions to interior decoration
Puff ready for some music
When measuring speakers I have used cardboxes, carpets and such in front of speakers to dampen the first floor reflection.
Useful both for indoor and outdoor measurements, this proves to at least have some effect on the reflection, improving measurement accuracy in a quick set-up.
Now, could a similar approach be used in an ordinary room, and actually look nice and appear as a natural extension of the interior design.
How Loud is it – Sound pressure requirements for movies and music
So, how loud is it.
What kind of sound level exposure is to be expected, and what sound pressure level should be used for system requirements.
