Hivi's audition disc cooking machine is OK, but at present, white noise and pink noise are the best and the most widely used cooking music, and the cooking machine on triple frequency is more comprehensive.

The cooking method is as follows:

1. Use some light music (white noise and pink noise are recommended), and let the headphones relax at a low volume. 10-30 hours, every four hours, and rest for about ten minutes before cooking.

2. Cook with ordinary music (except rock dance music) at medium volume 100-200 hours, in groups of four hours, and then stop for about ten minutes.

3. It should be noted that you can't cook continuously for a long time, and the machine pays attention to "asymptotic".

Actually, it's just like listening to music at ordinary times. Although it will be slower, the sound quality will gradually get better.
