Here are the formulas used in the calculations:

Voltage Calculation:Voltage (V) = √((10^(Loudness/10)) * Impedance)Where:

Loudness is the loudness of the headphones in decibels (dB).

Impedance is the impedance of the headphones in ohms (Ω).

Current Calculation:Current (I) = Voltage (V) / Impedance (Z)Where:

Voltage is the voltage calculated from the previous formula.

Impedance is the impedance of the headphones in ohms (Ω).

Power Calculation:Power (P) = 10^((Sensitivity + Loudness)/10)Where:

Sensitivity is the sensitivity of the headphones in decibels per 1 volt (db/1VRMS).

Loudness is the loudness of the headphones in decibels (dB).

To calculate the power consumption of headphones, you typically need to know the following:

  1. Voltage: The voltage supplied by the device (usually in volts, V).
  2. Current: The current drawn by the headphones (usually in milliamps, mA).
  3. Efficiency: The efficiency of the headphones in converting electrical energy into sound energy (usually a percentage).

Once you have this information, you can use the formula:

Power (in watts)=Voltage (in volts)×Current (in amps)Power (in watts)=Voltage (in volts)×Current (in amps)

And if you have the efficiency, you can account for it as:

Power (in watts)=Voltage (in volts)×Current (in amps)×Efficiency (as a decimal)Power (in watts)=Voltage (in volts)×Current (in amps)×Efficiency (as a decimal)

If you provide the voltage, current, and efficiency of your headphones, I can help you calculate the power consumption.
