I have 2 types of sound reflectors on the image attached. The angles are not proportional but you should get the idea. The black circle is the source, the black lines are the waves and the red lines are the reflections of the waves emitted by the source. My target is to reflect the sound waves so they end up parallel. Wich one will work? If booth work, Wich one do you think is better? And why? What material reflects sound best? Will the range of sound and amplitude rise using the reflector? Simple questions i know, but i just want to make sure. Thanks.
