I began a new hobby, I said, measuring the sound generated by a nearby South African military base (Air Force Base Ysterplaat). I have a professional sound meter. I knew that it would be loud. So far, I can say this: dBC is well into the 90s, meaning that the sound is above the harmfulness threshold, and is, well ... harmful to residents' hearing. It is louder than this -- but I have not caught the best moments for the sound meter. OBSERVATION: This is not of any concern to me -- I really don't mind the military aircraft -- it just happens to be my new hobby!
