How is attenuation different from gain in this calculator?

Attenuation measures signal strength reduction in decibels when the output voltage is lower than the input, while gain applies when the output voltage is higher; the tool uses the same formula but interprets the sign differently.

Can I use this calculator for audio or radio signal loss?

Yes, the tool computes voltage attenuation in decibels, which applies to any electrical signal including audio, radio, and telecommunications, as long as you have input and output voltage values.

What if my output voltage is higher than the input?

The calculator will return a positive decibel value representing gain; you can interpret the result as either gain or negative attenuation depending on your context.

Do I need to know the distance or material between input and output?

No, the calculator only requires the initial and final voltage readings; it does not model distance, cable type, or frequency effects.
