Calculator Signal-to-noise ratio for amplifier and headphones

According to the known parameter of the noise floor of the amplifier

Maximum voltage level at the output of the amplifier
Amplifier output impedance ohm
Noise floor of the amplifier
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
Signal-to-noise amplifier 0 dB
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
