    The fundamental frequency of the signal shall lie within the range 

70-525 Hz. The range of audibility of the signal from a whistle shall be 

determined by those frequencies, which may include the fundamental and/

or one or more higher frequencies, which lie within the frequency ranges 

and provide the sound pressure levels specified in Sec. 86.05.
