One interesting question arises out of studding these regulations.  Part 95 clearly defines the term "auditory assistance" ( see Sec. 95.1009 a. below in red text ).  Is it legal and common practice when applying federal regulations to interpret the definition in Part 95 as also applying to the use of the same term in Part 15 ( see Sec. 15.237 a. below in red text )  Please contact us if you can provide any information or insight.

Sec.  15.237  Operation in the bands 72.0-73.0 MHz, 74.6-74.8 MHz and 75.2-76.0 MHz.

    (a) The intentional radiator shall be restricted to use as an 

auditory assistance device.

    (b) Emissions from the intentional radiator shall be confined within 

a band 200 kHz wide centered on the operating frequency. The 200 kHz 

band shall lie wholly within the above specified frequency ranges.

    (c) The field strength of any emissions within the permitted 200 kHz 

band shall not exceed 80 millivolts/meter at 3 meters. The field 

strength of any emissions radiated on any frequency outside of the 

specified 200 kHz band shall not exceed 1500 microvolts/meter at 3 

meters. The emission limits in this paragraph are based on measurement 

instrumentation employing an average detector. The provisions in Sec.  

15.35 for limiting peak emissions apply.

persons with a physical or mental impairment that substantially limits 

one or more of the major life activities of such individuals;

    (3) Persons who may otherwise benefit from auditory assistance 

communications in educational settings.

    (b) Health care related communications for the ill.

    (c) Law enforcement tracking signals (for homing or interrogation) 

including the tracking of persons or stolen goods under authority or
