In the impressive interview between JP (a military serviceman) and Dr. Michael Salla (1,2,3) JP talks about the procedure of ‘memory wipes’ that would take place after people return back to Earth after their work on the Moon.

He says that he talked to a specialist who said that people who have certain ‘characteristics’ are more likely to withstand these memory wipes, and thus remember things that happened during their secret space missions (see 4). He mentioned things like having a spiritual life, affinity with music and sound, creativity and language.
The technique of removing memories would work with sound, amongst other methods.
In Megan Rose’s book ‘Welcome to the Future’ (5, 7) we learn that this practice of (sometimes temporary) memory wipes is common amongst many star races. There can be all kinds of reasons for memory wipes; in the example below Val Nek (6) wipes the memory of Megan’s encounter with them (and the abduction by other, not so friendly aliens) in order to protect a five year old Megan.
“Before he erased my memory with his cold hand to my forehead, he said this: ‘I am very sorry that this happened to you my dear girl. We will never let it happen again...” (5, p.16)
