To find out where the noises where coming from we placed recorders in different places. We figured that somewhere inside our house the noises would be clearest. It was a process of elimination. There were many different noises that we needed to identify. The noises of young children crying and screaming The sounds sort of an automated machine running around the clock The sound of motorcycles coming and going. By using 4 recorders we could place them in different locations and then playing them back we were able to establish where the noises were coming from. We tested everywhere inside the house. We also tested places outside the house. As an example we parked a car outside the front of Sophia nails in the parking bay over night. In the engine bay we dangled a recorder on a piece of string so that the recorder would hang just over the drain in that layby. On a different occasion we placed a recorder outside the house, between the rear of the house and the park behind. We wanted to work out where certain noises were coming from. We had established that the sounds of motorbikes were not coming from the street outside the house. When we compared the recorders we knew that the noises of motorbikes were coming from the rear of the house. I will go into more detail about the noises of motorcycles and the automated machines in the next episode. Best regards Alan ... https://www.youtube.com/watch?v=McWM1uj7IyM
