1. What is Headphone Voltage?

Headphone voltage refers to the electrical potential difference required to drive headphones at a certain power level given their impedance. It's a key specification for matching headphones with appropriate amplifiers.

2. How Does the Calculator Work?

The calculator uses the voltage formula:

Where:

• \( Power \) — Headphone power in milliwatts (mW)
• \( Impedance \) — Headphone impedance in ohms (Ω)

Explanation: The formula calculates the root mean square (RMS) voltage needed to deliver a specific power to headphones with a given impedance.

3. Importance of Voltage Calculation

Details: Knowing the required voltage helps ensure your audio source or amplifier can properly drive your headphones without distortion or insufficient volume.

4. Using the Calculator

Tips: Enter power in mW and impedance in ohms. Both values must be positive numbers. Typical headphone impedance ranges from 16Ω to 600Ω.

5. Frequently Asked Questions (FAQ)

Q1: Why is voltage important for headphones?
A: Voltage determines if an amplifier can provide enough "push" to properly drive headphones to desired volume levels.

Q2: What's a typical voltage requirement?
A: Most headphones need 0.1-2V for normal listening, with high-impedance models potentially needing 5V or more.

Q3: How does this relate to sensitivity?
A: Sensitivity (dB/mW) combined with this calculation helps predict actual loudness from a given source.

Q4: Can I damage headphones with too much voltage?
A: Excessive voltage can damage headphones by overdriving them, causing mechanical stress or overheating.

Q5: Does this work for balanced connections?
A: The calculation remains valid, but balanced connections may provide twice the voltage swing.
