#### This tool lets you calculate the sound pressure level (**SPL**) at the listening position from a single loudspeaker. Results are calculated while typing. Enter values. Speaker sensitivity: Amplifier power: Listening distance: Speaker placement: **dB** **SPL** (1W/1m) Watt: m Result. **SPL** at listening postion. Use this table to **calculate** SPL at a given distance to estimate loudspeaker wattage required to achieve desired SPL.

This usage returns a scalar value of **spl**_**dB** for the entire p_Pa signal. **spl**_**dB** = **spl** (p_Pa,ref,windowSize.
