I've been on many conference calls with technical difficulties. Either the PowerPoint presentation wouldn't load on the web conference, or the teleconference organizer put all of us on mute and then asked for questions (and couldn't figure out how to get everyone off of mute), or someone tried to stand outside by a freeway and listen to the call on their cell phone making the call practically inaudible. You know how it goes. We've all been there.
A few ways to reduce noise if you're facilitating or listening in on a conference call and the call will not be muted.
1. Call from a quiet location. Please don't try and join a teleconference from a room or place where there are televisions on, cars driving by, copiers running, folks typing on keyboards or talking on the phone, or in a public place with a lot of activity. This can be difficult if you work in a cubicle, so try to think about the best way to take part in a teleconference if that's your locale.
2. Avoid cell phones and speakerphones. If you have no choice, utilize the mute button. Unless you expect to talk through most of the meeting, it will be easier for other participants to hear if you take the responsibility of muting and unmuting yourself throughout the call. Usually this is not a complicated task, just a simple button on and off.
3. Use quality headsets to avoid a "tinny" sound. Avoid low-quality cordless phones as they sometimes create a buzzing background. Most offices provide quality headsets, but if you're attempting to call into a teleconference from your home or from another location, take care to find the best quality phone you can find.
4. Don't use the hold button if your phone system has built in background music or announcements. Just use the mute button instead. That way, you can hear what's going on, but no one can hear you. If you have to take another call, just leave the teleconference to do so. And of course, if you don't have to take the call right at that moment, just let it go to voicemail.
5. Avoid multitasking, such as paper rustling or answering emails, which are picked up by phone. It's hard to resist when the call seems to go on and on and you have many pressing things to finish before lunch. Once again, the mute button is our friend (I use it a lot when I answer email, eat food, or file papers while on certain teleconferences.)
Because audio quality is the most important aspect of most teleconferences, web conferences, and videoconferences, remember your fellow conference attendees the next time you all are on the phone line together.
