Once you have purchased the right sound from Sound Pharmacy, it will download in seconds. You can either listen to it directly online or on your MP3 or MP4 player. It can also be heard on your iPad, iPhone or other smart device. We recommend listening to your sound for a few minutes (mostly 5 minutes, as they are), twice a day (depending on your illness). in this way you will get the right “dose”. Don’t worry, we provide very clear instructions along with your healing sound download. These user instructions contain everything you need to know about your healing sound including how often to listen to it, the volume level required and even how to set most audio devices.
