Hi Bob, Yes, that was reported in the NY Times this morning. I did not see it--my noise level is higher than Lamont's because their sensor is several feet underground. This reduces the effect of wind and ocean waves. Both were high here--the surf was 3-6' because of the hurricane. Good to hear from you again.
