Customer: I think it may be radio interference since I'm high up on a hill.
Customer: replied 8 months ago.
Sounds like radio chatter usually hard to distinguish.
Only happens around this time, and the rest of the day there is nothing.
Customer: replied 8 months ago.
Also, it's only when I have earbuds plugged in, I don't hear it without.

Hi, I'm Pete. Welcome to JustAnswer! I'm reviewing your question now, and will post back with your reply ASAP.

There may be interference from a radio source; does the problem only happen at certain locations?

Customer: replied 8 months ago.
I have not had an opportunity to notice the problem in other locations, but it's only been noticed in the particular location.
Also, some days it happens and others it doesn't.
Customer: replied 8 months ago.
Would there be a way to shield the phone from interference?

Yes, in theory you could shield it from interference, however that would also prevent it from receiving and making calls, messages, etc.

Customer: replied 8 months ago.
That's fine if I have control of when the shielding takes place.
I heard that aluminum foil is able to do this, would that be correct?
Customer: replied 8 months ago.
That's mechanical based however, is there a software based solution or would that be inefficient ?

No, software will not work in this instance.

It must be a physical barrier. Aluminum foil will block radio frequency waves so it will work.

Since aluminum is a conductor of electricity, it forms a barrier often called a Faraday Cage, entirely stopping the radio waves.

Simply get a sheet of aluminum foil, and wrap the cell phone in it.

I have another question before I do so however, would I make a casing around the phone itself or should I also include the earbuds/headphones.
I feel that the earbuds acts as an antenna.

The ear buds are not connected to the antenna, they are only connected to the audio circuitry so they do not need to be covered.

Customer: replied 8 months ago.
Also it's more likely to be interference and not something malicious (just to be certain)?

If it only happens in certain areas then yes it is interference.

Customer: replied 8 months ago.
It also happens only when audio is playing, why would that be (just curious)?

It is because the speaker is active and picking up interference.
