Dover,
Yes.....polished stone and glass are reflective materials.
Every auditorium, performance space and listening room requires a blend of reflective and absorptive materials.
For drama.....the requirement for reflective surfaces to absorptive is different than for the performance of large scale orchestral works and this can be calculated quite accurately by acoustic engineers.
In my listening space....I have a 3.3mx3.5m heavily texture wool rug occupying 53% of the floor area. Semi-absortive cushioned furniture occupies another 20% of the floor area.
The wall behind the speakers is masonry and thus, generally reflective whilst one side wall is acoustic plasterboard with 50mm fibreglass insulation in the studwork on top of solid masonry. The rear wall is uninsulated plasterboard allowing for reflection of higher frequencies whilst allowing mid to low frequencies to pass through.
The one wall of thin(6mm) glass....allows the reflection of higher frequencies whilst passing all lower frequencies. The two sliding glass panels allow me to hear the effects of reflection by opening half the wall in a variety of infinite proportions.
There is a flat plasterboard soffit 2.7metre high(9ft) directly over the speakers and then a 5.7metre(19ft) cathedral ceiling which slopes down to the listening position.
Do you believe you can estimate what this room sounds like?
Oh.....and I've listened with the glass coffee table in and out and much prefer it in!
Am I wrong?
