Calculator Signal-to-noise ratio for amplifier and headphones

According to the known signal-to-noise parameter of the amplifier

Maximum voltage level at the output of the amplifier
Amplifier output impedance ohm
Signal-to-noise amplifier dB
Reference Volme Level dB SPL
Sensitivity of headphones
Headphone impedance ohm


Calculate


Signal-to-noise at reference volume 0 dB
Sound pressure from the background noise of the amplifier 0 dB SPL
Amplifier output voltage 0 dBV
Noise floor of the amplifier 0 dBV
Lowering the volume from the maximum to the reference level 0 dB
Voltage reduction due to the interaction of the impedances of the amplifier and headphones 0 dB
