Outgoing voice amplification: How can I amplify my voice over a phone call?
How can I amplify my voice over a phone call?
Communication is fundamental to participation in the working world and maintaining quality of life. For individuals - like your employee - who speak in a whisper, or at low volume, amplification devices can make a big difference for staying included in conversations. While there are many options for amplification devices for in-person communication, there are fewer options for phone conversations.
Some individuals have successfully used these traditional amplification devices in conjunction with a speakerphone call. Unfortunately, the nature of the microphone and speaker placement on both devices can lead to screeching sounds from the microphone’s feedback loop. One way to avoid this is to isolate the microphone that receives the softer voice by using a headset. The positioning of a sensitive microphone close to the mouth can increase the volume without needing to employ an amplification device at all. We have listed some headsets that shelter the microphone from background noise and can be positioned close to the speaker’s mouth.
