Every once in a while, we drop an interesting show into our feed that we think you’ll like.

This week, it’s “Twenty Thousand Hertz” - a show about the world’s most recognizable and interesting sounds.

The show’s title comes from the highest frequency that can be perceived within the human hearing range.

In this episode, host Dallas Taylor explores the world of advertising jingles.

They used to be an advertising staple, but these days, most have disappeared.

Except - for insurance company commercials - that are bucking the trend.

It’s an interesting sonic journey - and Under The Influence host Terry O'Reilly makes a special appearance.

Enjoy.
