Class 68 number 2 end is quite noisy. With the cooler group behind you at 100mph, hearing the DSD could be quite a challenge....

Yes it is exactly the same situation with Turbostars. There used to be a MCB that we could trip out to get some peace and quiet but is was removed for the reason you quote

Same with our Turbostars yet the Alstom 334's have a similar system but include an "off" position. No one can explain why its ok on a 334 but not a 170.
The Class 360 has the same ability to switch it off, frustrating as the sound annoying after a while on an Electrostar. I'm not that comfortable with a metal plate being installed over a MCB to prevent it tripping I(or being tripped) either!

Just a guess, but Alstom may have realized how irritating the constant fan noise would eventually get and included the 'Off' switch for that reason.
Again, that's just a guess...

I'm surprised that got past the Unions surely at that sort of sound level for potentially a long period of time hearing damage has to be at least a slight concern? Or is the DSD just really quiet

Just a quick question; what is a DSD?
Driver Safety Device I believe.
As above plus it is also known as the vigilance or dead man's switch (that last one isn't very common any more I believe on the railway but I could be wrong!). Usually it's something that has to be kept depressed in order for the train to work and every so often will sound an alert requiring the driver to release and then re-apply the DSD otherwise it kicks in the brakes.
It's often a pedal under the driver's desk isn't it?
I believe that's usually the case. One of the reasons why you have to release and re-apply every so often as that proves that it hasn't just been weighted down as well as ensuring that the driver is still conscious and it isn't just them slumped on it.
After working class 67 locos for 3 years on a daily basis my left ear hearing capabilities were down by 20% from the medical I took prior to working them and it has remained the same ever since, however still within the standards required for train driving.

DSD - Drivers safety device - DVD drivers vigilance device, it is the latter that makes the beeping sound however they are linked and the same pedal is used.
Not with DSD (Driver's Safety Device), that is the 'vigilance' aspect of DVD (Drivers Vigilance Device).

Reading the OP of this thread I used to love the engine noises of any loco and it never caused me any problem/distress.
Hows that saying go again about a little bit of knowledge?
Thank you for the correction

Pedant mode
The DSD doesn't Make a noise because all you have to do is keep the pedal depressed, the DVD is what makes the noise after a minute or two of inactivity.
