Multiple posts -- abusive saturation of Kudoz
May I observe, with all due consideration and respect, that these multiple posts have become an apparent abuse of this section and imposes a 'time vampire' on its well-intentioned members.
Since your many posted subjects seem to involve a complex field within acoustical engineering, it may well be better all around if you instead did some web searches -- with English (i.e., www.dogpile.com) and Arabic (www.ayna.com) search engines -- and navigated within those results to appropriate bilingual glossaries and other references to that field of engineering.
Also, you might reconsider the wisdom and ROI on your energy and time invested in undertaking translation projects in a complex and technical subject area that apparently is unfamiliar.
