  1. @AnthonyBthanks for your reply, I wasn't sure what the other reply was getting at either. I was aware of this in BS5839-6, in my opinion though it just seems daft to not have part 1 & 6 standardised in regards to sound levels. I mean it basically says it itself to my eyes.... it states that not all sound levels is certain to wake everyone, and children and people under the influence will require greater levels, therefore in my opinion it would make so much sense to make part 6 a requirement for 75dB at the bed head. This would make the standard safer than now and would require a device in every bedroom in a domestic property. I know they say that there is no evidence to suggest lives are being lost due to this but the safer the better? also, don't know how they would even prove no lives are lost due to this?? if someone dies in a house fire, they don't know whether they just couldn't escape or never woke up in time?? its so flawed to me. Also what solid evidence is there anyway to show people wake easier in their home than a hotel? It doesn't sit right with me and is just my opinion but 55db when bedroom door shut is unlikely to wake those in their home when they've had good amount to drink and are knocked out big time, 85dB in the bedroom more than likely would however.
  2. Hi, I'd like to know what everyone's thoughts are regarding why the requirement of bs5839-1 is 75dB at the bed head but 5839-6 is 85dB at the door (as is the evacuation alert standard). 85dB at a door could easily be 55dB at the bed head with the door closed, 20db lower than what part 1 requires. I asked tom brookes owner of Zzues training who is chairman of FSA and more. He said he had tried to get them to standardise and make it the same but it fell on deaf ears. does anyone know the reasoning behind it? any scientific reasoning? how has someone come to the conclusion a low sound level is enough to wake you at home but in a hotel it needs to be much higher? thanks
