Will my neighbours hear it?

Not if the building is built to stop it, which is a design decision rather than an accessory. Sound needs mass to block it, and insulation alone will not do the job. We use a heavier wall and roof build up, isolate the floor so impact noise does not travel through the ground, seal the doors properly and specify the glazing for acoustics as well as heat. Where the building sits matters enormously and costs nothing to get right.
