[Tigers] Clear Hooters

Tom, 


Thanks for sharing your thoughts on this. I agree with everything you have said. Unless there is/was a federal saftey standard for this sort of thing, as a practical matter I cannot see much difference either. I like your reasoning regarding the wider dispersion of the lower frequency horn. It is a theoretical reason for handing, although at the frequencies involved it may not make much difference from a practical sense. It also occurred to me that given the RHD world from which the cars came, they were setup for context, if a distinction was made at all. As an aside, it would be curious to know if the Alpine owners have noticed anything meaningful on the placement. 


I cannot see this being a concours issue either, although it would be easy enough to check without a frequency analyzer. The lip of each horn has either a fairly large "L" or "H" stamped on the front bottom part of the opening and easily can be seen through the grill opening. Maybe next time I am at a national event I will make my own little survey. 


FWIW, physically, the horns are mirror images of each other with spirals/snail trumpets that square off at the front. 


In any event, I am just moving on. 


Thanks again, Gene

I do not know what the factory installation was of the low/hi horns. 
However, there is some (probably very, very) minor logic to what I'll 
present: 

The lower the frequency of a sound, the more unidirectional it is. The 
higher the frequency the more directional it is. So, assuming the purpose 
for the horn is to alert say... someone running into the street (as an 
example) it would make sense to have lower frequency horn on the drivers 
side (USA). The reason being the added side distance to the person would 
better be heard by a lower frequency. That reason is probably ridiculously 
nit picky on my part, but the only reason I can see for having a 
determination for horn placement. And, if it were actually true then the 
country of shipment would have different horn locations based on what side 
of the road was driven on. 

If the horns have different physical structures (I don't know) then I can 
see the need to place them as shipped for concourse accuracy. On the other 
hand I don't ever recall a frequency spectrum analyzer ever being used to 
determine judging points at a car show. It may be there was no 
determination at the factory. I'm not saying it is wrong to strive for 
accuracy, only that it might not matter. I hope you do find an accurate 
answer. If so please report back because now I'm just curious. 

This subject does make me wonder if the infamous "Road Runner" horn(s) 
were of different frequency or they just had a slight, overlapping delay of 
the same frequency.
