Here's some advice from the American Speech-Language Hearing Association:
"Pipe down, please! - voice strain prevention
Healthy & Natural Journal, Oct, 2000
Trying to carry on a conversation at a noisy ball game or amusement park may strain your voice. In an effort to prevent laryngitis and vocal cord damage, the American Speech-Language Hearing Association is offering the following advice:
* Avoid yelling. If you feel strain in your neck or throat, you're too loud.
* Avoid constant throat clearing and coughing.
* Don't try to talk over noise.
* Avoid irritation caused by smoking or drinking alcohol.
* Drink lots of clear liquids."
