AUDIBLE TECHNIQUES FOR THE PERCEPTION OF NON-DESTRUCTIVE EVALUATION INFORMATION

摘要

Receives information contained in typical instrument signals in the form of amplitude, frequency, and time characteristics, and converts this information into sound quality and sound characteristics that can be perceived by humans, and thus the sound and pattern of the human auditory system Methods and apparatus have been disclosed that utilize cognitive abilities. The method and apparatus digitizes analog amplitude, frequency, and time information and selects appropriate acoustic characteristics that can encode this information in a standardized form that can be perceived by humans. This method allows the tester to test or inspect the material using nondestructive evaluation techniques in a way that allows the investigator to interpret the information provided by the test apparatus entirely through hearing, or in conjunction with sight and hearing. .
