Noisy hands free vibration sound

[Minimucks]

So, I have the comfort dash and place my phone in the small compartment above the drinks holder.
A few times under medium acceleration from standstill the person on the other end of the phone questions 'what's that loud rumbling sound'?

I do seem to get a slight resonating sound almost like a faulty lower engine mount is worn but it's been checked and it's fine as expected. 2019 van with almost 7k miles. Lowered on b14's and h&r arb's. Discovery media with app connect.

Does anyone else have have similar issues or ideas how to eliminate this?

I have nothing like this. Is it mainly heard by people listening on the other end of the phone or do you hear it when driving along?

Other end of the phone. I can feel a slight vibration(although that's clutching at straws a bit).

Could it be the air conditioning fan resonating down the phone?

Too cold for air conditioning in the UK at the moment

I have mine on all year around, it dries out the air keep windows clear even particularly in cool weather. The other possibility could be just resonance from the engine /gear box, as it is not very far away. Try mounting the phone somewhere else away from the dash. I never use a phone in the vehicle, in fact I rarely use one at all, if I can help it.

I am wondering if your phone is picking up induction raw. This would be more prevalent when accelerating. My vehicle is an Executive and so fairly quiet but under acceleration occasionally one may hear something like a rumble which I take as the turbo sucking in air but it is not obtrusive at all and I probably just filter it out as it is not an unusual sound.
