คำถามที่พบบ่อย

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.
