This really depends on the model you buy. If you buy a manual meat slicer, like the Befen Manual Frozen Meat Slicer for example, you don't need to worry at all about any noise issues as there aren't any electrical components to generate noise while slicing your meat. If you invest in an electrical model, however, noise can become more of a concern. Some meat slicers can get quite noisy while in operation, but others, like the Ostba Meat Slicer, remain relatively quiet while slicing meat. If noises tend to bother you quite easily and you'd prefer to keep things as quiet as possible in the kitchen, you may want to consider a manual meat slicer.
