As we explained before, dBA is just decibels adjusted to take into account the human threshold of hearing (we dont really hear sound below 1 kHz). Although the decibel value is the same, the perceived loudness is much different because of the frequency. For example, if the dishwasher has a powerful motor, it will likely be louder than one with a weaker motor. The loud noise damages the cells and membranes in the cochlea of the inner ear. The contours demonstrate that our ears become less sensitive at lower frequencies. If we want to define how loud is 55 decibels, lets take some examples. The dB scale is logarithmic, meaning that a 10 dB increase actually means that the sound level perceived is doubled and a 10 dB decrease means that the sound level perceived is halved. The sound of a typical human voice or a typical business office ambience would measure to be 60 decibels. They will also be affected by the time of day when the disruption happens.
