Speech understanding in the presence of background noise can be assessed using novel hearing tests. One such test is a Masking Level Difference with Digits (MLDD) test, which is a clinical tool designed to measure auditory factors that influence the understanding of speech presented within a background of noise. The MLDD test can be used clinically to facilitate a determination of functional hearing. The MLDD test presents background noise using both monotic and diotic conditions.
