Do people prefer Audiobook with or without background noises/sound effects?

Hey, I write and produce my own audiobooks and would often use background sounds I record myself and then produce. I wouldn't go so far as to use actual moment to moment sound effects, but more atmospheric backing tracks like trees rustling, gentle breezes etc. Do you find these things add to immersion and improve the experience, or are they too distracting from the prose?

Update: Having followed along with this thread as people have commented, I am going to say it's about an 80/20 ratio for Against/For.

Generally, the people against are ABSOLUTELY against, and the people in favour are are not so passionate and could take or leave it.

IN CONCLUSION:

Seems like the best thing to do is NOT put any sort of extraneous sound in, and just stick to narrating the book well, as you'll only alienate people. Thank you to everybody who responded, you have been so very very helpful!
