Voice Volume Meter

A fun voice control game for kids. Pick a target zone, speak into the mic, and try to keep your voice steady — as long as you can.

How Voice Volume Training Works

The Voice Volume Meter uses your device's microphone to measure how loud you're speaking in real time. Volume is mapped to five animal levels — from Mouse (whisper) to Lion (shout). Pick a target zone and practice keeping your voice at that level. The streak timer rewards consistency: the longer you stay in the zone, the higher your score. Kids tend to find this a lot more engaging than just being told to quiet down.

Tips for Parents & Teachers

  • Use it before quiet activities. Set the target to Mouse or Cat before reading time or library visits.
  • Make it a game. Challenge kids to beat their best streak — turning volume control into a fun skill.
  • Practice "inside voice" vs "outside voice". Use the Normal level as the indoor ceiling and Dog for outdoor play.
  • Celebrate consistency, not silence. The goal isn't to be quiet — it's to match the target zone consistently.

Four color-coded zones, session stats, and a calibration note

The meter now shows four labeled threshold zones: Whisper (≤30 dB), Conversation (30–60 dB), Loud (60–85 dB), and Concert (85+ dB). Each zone has its own color, so kids can see at a glance whether they're in the green or pushing into red — without reading a number. A session stats card tracks max dB, average dB, and recording duration in mm:ss. It resets when you stop and start a new recording.

Important: the numbers shown are relative dB from your browser's getUserMedia input, not calibrated Sound Pressure Level (SPL). A quiet mic in a loud room can read differently than a sensitive mic in a quiet room. The zones give useful relative feedback — Conversation vs Concert is clear, but don't use them to check OSHA compliance or hearing-damage risk. The animal levels still drive the game; the dB numbers are context.

When to Use a Voice Volume Meter

Use a voice volume meter to calibrate your microphone before recording podcasts, video calls, or voice-overs; train public speaking (aim for 65–75 dB in a quiet room); help children understand "inside voice" vs. "outside voice"; set appropriate volume levels for classrooms; and monitor your speaking volume during virtual meetings to avoid background noise complaints.

Voice Volume Reference Levels

Typical voice levels in decibels (measured at 1 metre): Whisper: 30 dB. Soft indoor conversation: 45–55 dB. Normal conversation: 60–65 dB. Raised voice: 70–75 dB. Loud speech: 80 dB. Shouting: 85–90 dB. For podcasting and voice recording, aim for peaks around −6 dBFS with average loudness around −16 to −23 LUFS (broadcast standard). For video calls, 65–70 dB at the microphone is typically ideal.

Frequently Asked Questions

Does this tool record or save my voice?
No. The audio is analyzed entirely in your browser. No sound is recorded, stored, or sent anywhere, the microphone stream is discarded as soon as you stop. Nothing leaves your device.
What age range is this designed for?
It works great for kids 3 and up, but adults use it too — for vocal warm-ups, speech therapy practice, or just for fun. The animal levels make it intuitive for young children who don't yet have a feel for decibels.
Why does my browser ask for microphone permission?
The tool needs microphone access to measure your voice volume in real time. This is a standard browser security prompt. You can revoke permission at any time in your browser settings.
How are the volume levels calibrated?
The animal levels are inspired by the NIOSH decibel scale used in occupational health. Mouse corresponds to a whisper (~30 dBA), Cat to a soft voice (~30–60 dBA), Normal to everyday conversation (~60–85 dBA), Dog to a loud voice near the hazardous threshold (~85–100 dBA), and Lion to shouting (~100+ dBA). A power curve maps your microphone input to these zones so that common speech volumes are clearly separated, and so the jump from Cat to Dog feels intuitive, not arbitrary.
How do decibels work — is 80 dB twice as loud as 40 dB?
No. Decibels use a logarithmic scale. A 10 dB increase represents roughly a doubling of perceived loudness. So 80 dB is about 16× louder than 40 dB (four doublings). A 3 dB increase doubles the sound intensity (power), but only sounds about 1.4× louder to human ears. This is why small dB differences in audio production can have significant perceptual impact.
What microphone level is best for video calls?
For Zoom, Teams, and Google Meet: speak so your voice peaks at −12 to −6 dBFS in your recording software, or roughly 65–70 dB SPL at the microphone. Avoid clipping (levels hitting 0 dBFS), it causes harsh distortion. Most video call platforms apply automatic gain control (AGC), but starting with a good level prevents the AGC from amplifying background noise when you're silent.
