I appreciate to sound the screaming 60's made back in the day. I enjoyed my share of that sound.

However if one has been around the game since then he should remember that it was that same scream that was blamed by many as the main reason for lost flying sites. We were considered bad neighbors. That started an evolutionary trend for noise reduction that has continued strong for about 3 decades. Enter rubber iso mounts, better muffling, much better props, operating engines at much lower rpm and most importantly, turnaround flying. TA style was THE style that promised noise footprint reduction and, in theory, should have led to flying site protection.

All of that AMA (and Pattern) led campaign helped only in the more crowded areas of the country of course. Open space fields could care less. Wish I knew what the break down was between those who were actually helped by the noise reduction campaign of the past and those that were not.

Four-stroke operation, particularly the current big blocks from YS, still can get noisy if the operator has not taken proper measures, but not the same as the screaming 60's. Electrics are about the easiest to quiet down; I understand the allure of the 60's scream to some.

Health-wise, I'm convinced that the engine runs back in the day directly affected my hearing. I've permanently lost the ability to hear certain frequencies. The constant humming (and sometimes buzzing) of tinnitus is always with me since about 12 years ago. You young guys beware of this problem
