The short answer: a first round of SSP Core usually takes five days of listening, roughly an hour a day, though it's fine to break that into shorter 20 to 30 minute sessions if an hour straight feels like too much. Most people finish their first full round within one to two weeks, depending on how consistently they listen.
SSP isn't a daily habit you build over months, like meditation or journaling. It's closer to a short, intensive retraining period for the muscles in your middle ear, which is why the core protocol is designed to be short and specific rather than open-ended. Once you finish a round, you're not expected to keep listening indefinitely.
Some people feel a difference during the listening itself, a kind of settling. For most, the more noticeable changes show up in the two to six weeks after finishing, better sleep, less reactivity, an easier time focusing or connecting with people. It's not usually instant, and it's not usually nothing either.
For most people, the effects of a single round tend to soften somewhere between 8 and 12 weeks, especially in the first year. That's normal, not a sign it didn't work, it's part of why a longer access window, not a single one-time session, matters more than people expect going in.
That's common, and it's fine to go slower. There's no deadline once you have access, and shorter daily sessions work, they just stretch the timeline out a little.
