Frequency Response Measurements for Cassette Tape Players
Abstract
Automotive cassette tape players made by 21 companies were surveyed to determine a prototype unit that may be used as part of a mobile bird dispersal system to help reduce the USAF bird-strike hazard. Nine units were selected on the basis of the manufacturer's specifications and tested for frequency response. The three with the flattest measured response were then used to record audio sonagrams from taped recordings of four bird distress calls. These tests indicated that, of the nine players, the three exhibiting the flattest frequency response were the Hitachi Model CS-200, Pioneer Model KP- 300, and Realistic catalog no. 12-1823.
