I have listened to Holosync's quietude soundtrack while photoreading and activating. I found that it helped me reach the accelerative learning state quicker while holding me in that state throughout the duration of the track. I think it is definitely beneficial, however, I no longer use quietude to achieve the ALS because I personally felt that it could lead to a crutch. I am continously trying to use PR in all the different environments I come across. For example, I PR in public libraries, bookstores, work, home etc. Personally, I felt that it would be easier for me to adapt to those surroundings without having to be reliant upon quietude as an aid.
