How effective are high audio frequencies in commercials in getting audience attention? Does anyone know of a peer reviewed article that describes how commercials will often contain high audio frequencies in order to attract the viewer's attention?

Referrals to commercials using any audio based method to command attention would also be welcome.

I believe this will come under the field of psychoacoustics.
I am not aware of any use in using "high audio frequencies" in commercials, but there is a history of making commercials louder (presumably to attract attention). There are laws prohibiting increasing the loudness of commercials  (e.g., CALM Act). Increasing the loudness, without remotely adjusting the volume on the TV is not a trivial thing and potentially involves careful mixing of the audio signals as well as allowing acceptable levels of distortion.
