Why is it difficult to classify hydrogen as a metal or non metal?
what are you trying to do or eliminate ? thin metal will vibrate making sound pass 'through' it thick metal will deaden sound as the vibrations of the music are not able to vibrate the metal so therefore the sound is 'killed' much the same way a wood wall will vibrate and a brick one will not
It depends on how it is used. You can buy speakers with metal cones. You can also place a small metal object like a candle holder on a sub woofer, and it will vibrate like crazy and make a buzzing sound. You can put a metal plate in front of a speaker, and if it is dense enough, it will deflect the sound back at the speaker.
You need to be more specific on your ? Do you mean sound reflecting off metal? For an example: If you have sound sytem in your living room and you have hardwood floors you would get better sound with your highs opposed to carpet.
properly, you are able to not boost some thing without including power so i'd say its no longer plausible to enhance the sound that way. What you need to do is: a million) Direct the sound to the persons as a lot as plausible, it is done through acoustics that concentration sounds from one area to a unique. it is fairly in the layout of the progression. you need to sit down the speaker in a shell or parabolic dish which will direct alll sound from them outward 2) get rid of extraneous sounds - make certain outside noises are minimized and dress reflective surfaces with soaking up resources to mimizine distracting echos, you would lose some volume besides the undeniable fact that it is going to likely be more beneficial sparkling. also you need to furnish seating it is silent for the target audience, pad the chairs and make certain they don't creak at the same time as people shift (oil them) 3) paintings with the speaker on supported projection. it is what authentic singers/voice professionals do. they want to push their words out utilising their diaphram and not in any respect their throat. Have them lay flat and placed their hand on the area decrease than their ribcage and make themselves breath in trouble-free terms with their abdomen (no longer chest). This forces the diaphram to flow alot and they could experience what its like. The have them practice felxing this muscle and utilising it at the same time as talking. you'd be astounded at how loud un-amplifed voices would properly be (opera singers) at the same time as precise experienced. And this practise will forestall you from getting hoarse over the years and ruining your voice. at the same time as talking or making a music in this kind your sound will be finished (supported) and project out from you with little attempt. that is my handle it, like to make certain another solutions
