Loudness discomfort levels (LDLs): group data of<unk>  patients without hearing loss. Upper line: average hearing thresholds. Lower long line: LDLs of this group. Lower short line: LDLs of a reference group with normal hearing. The basic diagnostic test is similar to a normal audiogram. The difference is that additionally to the hearing threshold at each test frequency also the lowest uncomfortable sound level is measured. This level is called loudness discomfort level (LDL), uncomfortable listening level (UCL), or uncomfortable loudness level (ULL). In patients with<unk>  this level is considerably lower than in normal subjects, and usually across most parts of the auditory spectrum.
