Will give brainliest to whomever helps me get the correct answer first. Please help! Explain why a mirror is good for seeing objects and why acoustic panels are used in concert halls.

Nothing can make or break the sound of your performance, your rehearsal space, a recording venue or a home entertainment system more than room acoustics. You may have the very best instruments, speakers, amplifiers and recording equipment and you may have placed it all perfectly in your space, but if your performance/recording/listening room has poor acoustics, you’re really facing an uphill battle.

Luckily, there are a lot of things you can do to improve even the worst spaces. Remember that old cliché, “Moderation in all things”? Well, that applies to room acoustics too.

What you want to do is create a room that is neither too “live” nor too “dead.” A “live” room is a room with a preponderance of hard, reflective surfaces. Lot of exposed glass windows, hardwood floor, things like that. The room sounds like your high school gymnasium—things seem to echo forever. (See figure 1.) Those excessive echoes make it hard to distinguish between individual instruments and vocalists in the music. Everything smears together in a harsh cacophony of overly-bright, hard-edged sound. The original warm, organic sound is lost and you’re left with a shrill, indistinct, tinny caricature of what the music should sound like.

Answer

Mirrors reverse the direction of the image in an equal yet opposite angle from which the light shines upon it. This allows the viewer to see themselves or objects behind them, or even objects that are at an angle from them but out of their field of view, such as around a corner.
