> For regular in-room speakers, the amount of bleed depends on the relative placement of the speaker and microphone, the directionality of both, the volume of sound from the speaker and the sensitivity of the microphone.
And on how much reverberation there is in the room. If there's a tile floor, a brick wall, and no furniture with upholstery, sound is going to find some path from the speakers to the microphone no matter the placement and directionality.
If you have carpet or a rug, maybe a couch or bed, etc., then some of the sound will get absorbed before it can get from speakers to microphone.
