Certain sound frequencies to induce mind moods

[luxtpm7]

When i was a kid i read the first book on hitscock the 3 investigators Bob Pete and Jupiter the castle of terror where everytime they would go to the castle they would be terrify, in the end an old movie star would have been hiding in the castle and scare people by using a certain no audible frequency

15 years ago i heard on the news that certain acid music was banned since it induced changes in mood by using certain frequencies

Im interested in some link or info that deals with this subject

You're referring to "infrasound". low frequency sounds less than 20 Hertz. I doubt any music was banned due to it, but it is said to induce a variety of strange sensations and feelings.

Just do some googling on it.
