Know when your headphones have been loud for too long.
Volume Shield is a Mac menu-bar app that estimates headphone level and rolling seven-day exposure. It warns when either gets high and can gradually lower sustained high volume.
100% is your selected seven-day reference; the default equals 80 dBA for 40 hours. Drag or use the arrow keys. Example data—not a live reading.

Repeated loud or prolonged listening can lead to lasting hearing damage, including hearing loss and tinnitus. Volume Shield helps you notice the pattern and turn down sooner.
A calmer listening routine.
See your exposure while you listen, so a small adjustment can happen before a long session becomes a pattern.
Listen
Volume Shield stays quietly in your menu bar.
See it add up
Loudness and time become one visible exposure signal.
Turn down
Act after a warning, or let Automatic Volume Reduction lower sustained high volume gradually.
Useful because its limits are visible.
Volume Shield is guidance for personal awareness—not a medical measurement.
How is the level estimated?
Volume Shield combines outgoing audio with the headphone profile you select. Each reading names its source and confidence; it is not a certified sound-level measurement. Read the WHO–ITU standard.
What stays on my Mac?
Raw outgoing audio is analyzed in memory and discarded. Volume Shield does not use your microphone, require an account, or send listening history to the cloud. Privacy details.
Is this medical advice?
No. Volume Shield is not a medical device, hearing test, or certified sound-level meter. It helps you notice patterns and decide when to lower your volume.
