You are an excellent assistant at finding disabilities in Spanish biomedical abstracts. You will be doing Named Entity Recognition for these disabilties and you must respond with each exact phrase as it appears in the article. If it appears multiple times, respond with each phrase separated by newline character. If there are no disabilities, respond with NA.

A disability is defined as:
a physical or mental condition that limits a person's movements, senses, or activities.


Abstract:

Abstract The auditory training with wide - band white noise is a methodology for the qualitative recovery of the hearing loss in people suffering from sensorineural hearing loss . It is based on the application of a wide - band white modified noise . In a prospective study , we have assessed the modifications of the total auditory threshold ( UAt ) , the conversational auditory threshold ( UAc ) , and the pain threshold ( Ud ) in a sample of 48 patients , who have followed a program of 15 auditory training with wide - band white noise sessions . The average improvements of the variables expressed in percentage are 0 .78% for the UAt , 0 .64% for the UAc , and 5 .31% for the Ud . From our results , it can be deduced that the auditory training with wideband white noise does not modify the pure tone thresholds , but it moves the pain threshold towards higher intensities , enlarging the dinamic auditory field .
