"To camouflage" is to sight as "to ____" is to sound

I am looking for a word that describes disguising or hiding sound with other sound. Much in the same way that camouflage acts in hiding visual objects.

I ______ our conversation with loud music to avoid recording.

What could be used for hiding one sound under another ?

I muffled our conversation with loud music to avoid recording

This is the first word that comes to mind, and has a similar connotation with sound that camouflage has with sight.

From Oxford English, see the second definition with emphasis added.

muffle

VERB [WITH OBJECT]

1 Wrap or cover for warmth. 'everyone was muffled up in coats and scarves’

2 Cover or wrap up (a source of sound) to reduce its loudness. ‘the soft beat of a muffled drum’

From Merriam-Webster, see the first definition and the second part of the third definition with emphasis added.

muffled; muffling

transitive verb

1 to wrap up so as to conceal or protect : envelop

2 obsolete : blindfold

3 a: to wrap or pad with something to dull the sound. 'muffle the oarlocks'

3 b : to deaden the sound of

A comment by mahmud koya also noted this word and usage.

you could consider "drowned out"

I drowned out our conversation with loud music to avoid recording.

For a single word "masked" would work equally well.

The best word I can think of is sound masking, which can be used to disguise one’s voice, as camouflage can be used to disguise one’s appearance.

Wikipedia on Sound masking

Addition of sound created by special digital generators and distributed by normally unseen speakers through an area to reduce distractions or provide confidentiality where needed

Since sound masking is two words, you can use masking while talking in the context of sound.

Masking - The process by which one sound is used to obscure the presence of another.
