常见问题
Quick answers.
›What reference levels are used for dB calculations?
The converter defaults to a reference pressure of 20 μPa for calculations in air and 1 μPa for applications in water or other media.
›What is the relationship between pascals and decibels?
Sound Pressure Level (SPL) in decibels is calculated as `20 * log10(p / p_ref)`, where `p` is the measured pressure and `p_ref` is the reference level.
›Can I convert between different pressure units?
Yes. The tool supports linear conversions between pascals (Pa), micropascals (μPa), millibars (mbar), and microbars (μbar).
›Is my data processed on a server?
No. All acoustic conversions are handled by your browser's local processor, ensuring no data is transmitted or stored externally.
