Tonights noise

Again a humming fan like noise tonight.

Began to notice it about 8pm.

Can hear it in our living area which faces north and in our bedroom upstairs.

It's annoying as it makes it hard to get to sleep

Will be very annoying when weather warms up and we want to be in backyard in evening for bbq etc.

Prior History of Noise for Us

We live in Vautier Street since 2007. When we moved here we noticed no industrial noise.

The summer before last (09/10 Summer) was when we first noticed the noise from the nearby industry. That summer we noted very frequent fan like noises from our nearby industrial area and discussed this with our neighbours. This was a whooshing sound which was worst at night (whoosh, whoosh whoosh), we're not sure if someone made a complaint to someone but it went away after a few months. In the last 3-6 months a constant humming noise (like a fan noise) has become more consistent and audible. We're not sure where it comes from but we think it might be from where the grain is unloaded?? We can hear it all day but I have noticed on Sundays past that I haven't heard it at all. On other days it is most noticeable in the morning and the evening and night time. It seems to become worst when the road noise from Melbourne road dies down for the evening. It keeps us awake sometimes and is annoying when we are in our backyard.
