I can't help feeling that your rather pompous analysis is flawed from the outset, too narrow in its view, and looking from the wrong viewpoint - namely, a solution in search of a problem. You should also be aware that the use of Arduinos in projects like these has been made rather redundant by a new technology called human locomotion.
This technology comes in automatically configurable serial and parallel versions and has taken over in this arena because it is fully automatic, self-regulating, requires very little wiring and, barring accidents, is self-maintaining.
this is to be mainly focused on large auditorium or classroom,the sensors is to be placed near to the speakers.suppose there are 2 speakers one at front position and other at last position then there no need to be have an equal volume at the entire speakers the front position of the speaker have that sence of volume and the last position of speakers have at most volume to be heared by audience.By applying this technology there need not have a manually controlling of speakers...
Is it possible for you to break down your writing into separate sentences? Also, when you write "speakers". are you referring to people speaking or are you referring to devices to convert electric signals into sound?
Classic example of "I know what I am talking about so why doesn't everybody else?"
It is because what is inside your head is not outside it in the form of words. See all those full stops at the end of your words? How about distributing them amongst the words?
Words are great, they can convey meaning, but only if you pick the right ones. On this occasion you did not. Want to try again?
Looks like the threads have been merged and one, or more post of the OP removed. Thus making my reply #5 sound a bit odd as it was replying to a rambling start post which is now reply #3. I never saw the first post when I made my reply.
There's these things called microphones that people can wear and other things called amplifiers and speakers.
The person speaks, the microphone picks up the sound, the amplifier and speakers can make that sound come from other places than the person wearing the microphone. I know it sounds crazy but it's true!
More modern, the sound from the microphone can be broadcast to people wearing headsets or ear buds via radio/bluetooth.
Too much volume can damage your hearing. So you seem to want to damage the majority of people's hearing to compensate for the few who are hard of hearing?
That paper is rubbish.
Is the OP trying to market a solution for a problem that doesn't really exist? If students in the back of a large lecture hall can't hear the lecturer, then they need to turn up the volume of the rear speakers. That's all.
I won't be assigning any major projects for about three weeks. There is plenty of theory and technique to be learned prior to Spring Break.
After the break, we'll separate the "wheat from the chaff". Students who are serious will continue to push. Those who are skating by, will look for the easy out, so they can coast 'til the end of the semester. A late project makes the final grade reflect this tendency.
I didn't know you teach for money. That's like professional sado-masochism isn't it?
I run the physical science laboratories for a two-year college. It's like having the world's biggest chemistry set, but with lasers, telescopes and robots thrown in for good measure. It's actually pretty fun. Once in a while I have to struggle, but for the most part, our students are eager to learn.
Not sure what to make of this project though. The question 'can an arduino do this', suggests that it's not very far along.
I think that feedback was used to regulate volume through circuitry long before I was born, and I'm older than transistor radio.
The real product which might exist would be an MP3 player/recorder with microphone, volume control and direct output to ear buds while recording to sell cheap to students. They can review the lecture or perhaps feed it to voice to text on their PC's and speed read to save time.
