Thank you for the opportunity to help you with your question!

Actually, there is an echo in a small room just as there is an echo in a large room.

An echo is what you hear when a sound that comes from you, or near you, hits a distant object and reflects back.

In a small room, the distance is very short and the reflected sound reaches you so quickly that you are not aware of it.

However, if you were in a small room where all the sound was intentionally deadened. You would notice the difference.

Please let me know if you need any clarification. I'm always happy to answer your questions.

Tutor went the extra mile to help me with this essay. Citations were a bit shaky but I appreciated how well he handled APA styles and how ok he was to change them even though I didnt specify. Got a B+ which is believable and acceptable.
