How to stop smells coming through walls

We can smell our neighbours cooking through a shared party wall. Is there anything that can be done to reduce smells coming through the wall?

"Hi Michael. Cooking smells are usually caused by air gaps rather than the wall itself. Best things to check are gaps around sockets, skirting, pipework and ceiling edges, then seal with caulk or foam. Also make sure the extractor fan is venting properly outside and filters are clean. If it’s a stud wall, adding insulation and acoustic plasterboard can help stop smells travelling through the cavity.
Hope this helps. Thanks Ryan"
