While accepting that the megaphone use be restricted to clinics, the applicant wishes to be able to use the megaphone for up to three hours per day during the clinics. It was said that the megaphone would be used intermittently throughout the course of the day, but more in the morning during dressage instruction, rather than for jumping in the afternoon. It was Mr Mitchell's submission that the type of megaphone used has the lowest output available (6 watts with a maximum capacity of 10 watts) and the megaphone had an audible range at a maximum volume of 200m in city or suburban conditions. He conceded, however, that the objectors would hear Mrs Leslie's voice through the megaphone, or indeed unassisted, from time to time, particularly when there was a northerly wind. He also said that having regard to the fact that the clinics may only be conducted on 12 days per year, and on some of those days the prevailing south-westerly winds (which would carry noise away from objectors' properties) would occur, the amenity impact for neighbours would not be unreasonable. He also acknowledged that while Mrs Leslie had earlier conceded use of the megaphone during clinics for only one hour per day, this concession had been given under some duress. Mr Mitchell indicated that his client requested that the 3 hours of use of the megaphone per day might occur within a modified time band of 9.15 a.m. to 4.00 p.m. (in contrast to the 10.00 a.m. to 5.00 p.m. referred to in Condition 8).
