New EB- Airy Sound Normal?

[Foxtrot]

Whenever I'm cruising without the accelerator engaged, I hear this small hissing sound like it's right behind the radio console area. Kind of like air whoosing through a small hose. Is that normal? Goes away instantly when the gas is applied.

Car's a 2017 ecoboost. just bought it last night

It sounds like what he is hearing is the bypass valve opening under mild acceleration which is totally normal.
