"Use a reasonable voice level--Don't raise your voice during in-person conversations or on the telephone.

Don't hold meetings in your workspace--If you've got time to schedule the meeting, plan to hold it in an appropriate setting.

If an impromptu conversation is going to take time, find an isolated location--Have you gotten onto a fascinating topic or into a heated debate? Move it out of your workspace and into a more appropriate location.

Don't talk or yell past your immediate neighbor--If you have to raise your voice to talk to someone two to three workspaces away, anyone else within earshot won't appreciate it. Go over to the person's desk, phone, or communicate electronically.

Don't use speakerphones--Not only will you raise your voice level, but those around you will hear the other side of the conversation as well. If you need to use your hands while on the phone, use a hands-free headset."
