Video transcript

Most people cannot hear a 1 dB difference. The minimum change in sound level that is generally noticeable by the human ear is about 3 dB. This means, in most practical situations, a 1 dB difference is not perceived, helping in scenarios where slight noise adjustments are needed.

Questions and answers

  1. What is the smallest change in sound level that can be heard?

    The minimum change in sound level noticeable by the human ear is typically around 3 dB.

  2. How does decibel measurement work?

    Decibels measure sound intensity, with 0 dB being the threshold of hearing.

  3. Why are 1 dB differences often undetectable?

    1 dB changes are generally too subtle for most people to perceive in typical audio situations.
