⚠️This is a relative loudness meter, not a calibrated sound level meter. Every device's microphone and settings are different, so readings will vary between phones/computers and aren't precise measurements. For hearing-safety decisions or any situation needing an accurate number, use a dedicated SPL meter instead.
