Some of the tiredness you feel after a day of video calls has nothing to do with the agenda. It comes from the work of listening through poor sound. A hum behind one person, a hollow room around another, a third whose words arrive slightly chopped: none of these stops you from understanding, so nobody complains. But each one forces your brain to fill in gaps, and filling in gaps for six hours is labor. Cleaning up the audio is one of the few fatigue remedies that costs little and helps everyone on the call at once.
Listening is work, and noise makes it harder
In a quiet room with a clear speaker, understanding speech feels effortless. Add noise, and comprehension survives, but it is no longer free. You start leaning on context to guess the word that was masked. You replay the last phrase in your head to check that it made sense. You hold more of the sentence in memory while waiting for it to resolve. Researchers who study hearing call this listening effort, and the everyday experience of it is familiar to anyone who has held a conversation in a loud restaurant and gone home tired.
The important point is that the effort is invisible. People rarely interrupt a meeting to say the sound is a bit wearing. They follow along, contribute less, and feel more drained at five o’clock without knowing why.
Why a call is harder than a noisy room
In person, your hearing has help. Two ears let you locate a voice in space and separate it from noise arriving from elsewhere. You watch lips and faces, which supplies a surprising amount of information about consonants. You can lean in.
A call removes most of that. Every participant’s voice, every background noise and every echo is mixed into a single stream that comes out of the same speakers or earbuds. There is no direction to separate them by. Lip movements on video are small, compressed and often slightly out of step with the sound. On top of that come the artifacts that exist only on calls: the brief dropouts of a struggling connection, the watery tone of aggressive processing, the volume that jumps between one speaker and the next.
Meetings also add up. One unmuted participant with a fan in the background is a minor thing. Four of them, in back-to-back meetings, across a week, is a steady tax on attention.
The small culprits
Loud, obvious noise tends to get fixed because someone objects. The noise that contributes to fatigue is the low-level kind that no one mentions. A laptop fan running under load. An open window. A large bare room that gives one voice a persistent hollow ring. Keyboard clatter from someone taking notes off mute. A speakerphone in a conference room that makes half the table sound far away.
Inconsistent volume belongs on the list as well. When one colleague is loud and the next is faint, listeners ride their volume control through the meeting, or give up and strain.
Most of these have simple fixes in the settings of whichever platform you use, and the guides at Call Tonic go through them for Zoom, Teams, Google Meet and Webex if you want instructions to pass around a team.
What an individual can do
Treat your own audio as a courtesy to everyone listening. Use a headset or earbuds with a microphone near your mouth instead of the laptop’s built-in one. Turn on the noise suppression that is built into your meeting app, and stay muted in larger meetings when you are not speaking. Choose a room with soft furnishings over a bare one where you have the choice.
On the receiving end, listen through decent headphones rather than tinny laptop speakers, at a comfortable volume rather than a high one. If a colleague’s sound is hard work, tell them privately and kindly. Most people have never heard their own call audio and are glad to know.
What a team can do
Habits set at team level have more effect than any one person’s equipment. Agree that mute is the default in meetings above a handful of people. Make a wired or wireless headset standard issue rather than a personal choice. In hybrid meetings, ask remote participants at the start whether the room is clear, since they are the only ones who can judge. Leave short breaks between meetings so that ears, as well as eyes, get a rest.
A cheaper fix than another wellness initiative
Meeting fatigue has several causes, including too many meetings, too much time on camera and too little movement, and better sound will not cure those. It does remove one steady drain that people have learned to tolerate without noticing. A few headsets, a settings review and a shared habit of muting cost very little, and the difference shows up in how people feel at the end of the day.
