I wanted to show other Hispanics of this different type of sound.

There are two basic types of sound: airborne and structure borne.

And there was a third type of sound, for his ears only.

Ultrasound is a type of sound with a frequency bigger than humans can hear.

This type of sound is very versatile and exciting.

"It is not just a roly-poly type of sound," he said.

Infrasound is a type of sound with a frequency lower than humans can hear.

They were not really interested in having a listenable type of sound.

Music is a type of sound that has some stable frequencies in a time period.

That type of sound was in keeping with the dramatic characterization.
