Sound transmission, particularly through glass
The legal side of this problem is with the local authority on the
grounds of Statutory Nuisance. The problem is that the recent owners of our neighbouring property have moved out of town with the philosophy they can live the country life style regardless of who is around them. Because we live in a rural situation 4 cocks crowing 25m away at dawn is regarded by them as the norm we should expect. One thing I have noticed particularly this year is that a new cock has a particularly high frequency shreek - this seems to penetrate further than previous ones - curiously worse through a dg panel rather than a a single glazed sash window. Is this awareness related to ear sensitivity at the higher frequency (1kHz?), or greater mechanical transmission due to the frequency ? Thanks for any comments Rob |

Here its normality for me to wake up at 4 a.m. every early summer day as the deafening dawn chorus comes in through the open windows. it lasts half an hour, then I go back to sleep. Until the first car of the day wakes me up around 7:30 a.m. again. Thanks for any comments Rob |

Thanks for any comments Rob Double glazing is optimized for heat, not sound insulation - although it may well be better than single glazing. But this is more down to the added mass of the second sheet of glass, rather than the gap. Secondary glazing, spaced as far as practicable from the main window and well sealed, would give the best results. Using as thick glass as you can. Assuming a standard 9" masonry wall, a sealed plate glass double window with one pane on the outside of the wall, one on the inside, would give results not far short of the wall itself. But none of this will help much in practice... -- *Husband and cat lost -- reward for cat Dave Plowman London SW To e-mail, change noise into sound. |

The drawing office where I spent a few months as an apprentice was close to the Midland mainline railway. Secondary glazing was said to be spaced at 7" to optimise sound reduction. Mind you, my ears have reached the stage where, when my wife asks *what's that bird? I say, what bird?. regards -- Tim Lamb |

Pilkingtons do laminated glass that has a thicker polymer layer which they market as a noise reduction aid but good luck finding any solid data on it, they appear to have wiped their websites clear of useful information. A while back I tracked down some detailed figures from one of their noise reduction studies, on pilkingtons.za I think, it showed that DG units of standard gaps with dissimilar glass types were good and ones with one pane laminated and one pane toughened glass were particularly effective. I think the dissimilar glasses broke up the resonances between the panes. Needless to say the frames need to be air tight with trickle vents foamed closed. -- fred BBC3, ITV2/3/4, channels going to the DOGs |

Us farmers have what are called *deemed consent* rights for most changes which would normally involve planning. Deemed consent - sounds as good as papal dispensations once were. Councils could raffle a few of those off, and make enough money to fix all the potholes. |
