In trying to raise the quality and popularity of AM broadcasting, a study explored listeners' attitudes toward transmission and receiver bandwidths. Results suggest that for highly compressed audio, such as rock or pop music, listeners heard very little difference between 7 and 10 kHz. However, for audio with fewer masking characteristics, such as speech and classical music, listeners preferred lower bandwidths of 5 to 7 kHz because they reduced real-world noise from adjacent channels. More is less; 7 kHz may be optimum for AM broadcasting.
