That should be the A/C clutch kicking in. Normally it should not be too audible. Seems like the clearance might have too large of a gap.

During acceleration the engine computer is progrrammed to disconnect the clutch to reduce the load on the engine for better performance and that is normal.

For noise problems we can help much as we are not able to determine the exact noise emitted and source. It is best to get someone to have a look at it.

If the noise is a single click when A/C is turned on, that should be from the clutch and whether it is normal or not depends on noise level.
If the noise is some sort of intermittent rattle, that can be due to the tensioner or a stretched belt.
