DAB Sensitivity

The minimum DAB or DAB+ radio signal needed to meet a stated decoding-quality criterion under specified test conditions.

DAB sensitivity describes weak-signal reception, rather than the noise of the analogue audio output. A lower required input level indicates greater sensitivity when measurement units and test conditions match. In dBm, a more negative threshold represents less input power.

DAB Sensitivity — Tuner

For a tuner, keep the radio band and test-channel model with the value. A Gaussian test channel and a fading Rayleigh channel represent different reception conditions. A quoted bit-error-rate criterion specifies the permitted proportion of incorrectly decoded bits, rather than a listening-volume setting.

Compare figures with the same units and criterion; dBm, dBµV and dBf are not interchangeable numerical scales. Better sensitivity can help reception of weak stations, but antenna installation and local coverage still matter. The rating does not guarantee reception throughout a region or describe the audio codec’s quality.
