the humming is worse than it was, sounds like our central heating boiler, but its not on, but no one is interested, the council make out is us, they are not prepared to bring their equipment again, even though it was 2 years ago, the noise is very loud in the morning from about 4.45am, then worse about 9am, is reasonably bearable in the afternoon, then about 3.00p.m starts again all evening, about 10.00p.m. starts loud, going on all night. Came in this morning Wed, about 4.45am and it was very loud, can hear it outside. We are at our wits ends, no one seems to want to help. Have read a letter on wed page, that says the councils are using shoddy equipment, saying they can't hear any noise so they don't have to spend money, taking factories to court, the law says everyone is entitled to peace in their own homes from 11pm to 7am, but we haven't had that for 3 years. still waiting for our local newly elected councillor to come and have a listen.
