Here's an online petition for BCF encouraging them to use the 3-tone whistle on their Coastal Class ships. Link to PetitionWe can forward it to them at a later date. If someone wants to write up a cover letter to send along with the petition (do I see Scott raising his hand over there?), they can do so.  |

If they asked why we were concerned about this, what would we tell them?

If they asked why we were concerned about this, what would we tell them? We'd say that it's simply our appreciation for sound aesthetics and nothing more than that. - so if the only reason that BCF is using single-tone is just that it's their arbitrary choice, then they will now know that some citizens actually prefer the multi-tone. ....and if BCF has an operational reason for using the single-tone horn, then our petition request is irrelevant and BCF should ignore it. But if it makes us happy, it doesn't hurt to ask, as long as we keep it in it's aesthetics context. (we're exercising our "Sheryl Crow rights" on this matter) ps: - I e-signed it, because it would make me happy. No harm in asking. |

Flugel said it well. Unless using the three-toned horn uses hundreds of dollars worth of extra electricity per day, then it's worth using them, just because they sound better. As of right now, there are 6 signatures. If you like the chordal whistle, don't rely on other people to sign it for you. The more, the better. It only takes 20 seconds to do. |

I used to be indecisive. Now I'm not sure.

Here's another question. Has anyone simply asked why they don't use the three chord tone?

While we are at it can we have a petition aimed at ditching the current drab livery and the slugs that goes with that?
Our ferry horns often sound bad, and the vessels themselves don't look too sweet either!

Is the three and one tone the same volume?

Is the three and one tone the same volume? Correct. Scott had mentioned in another thread that if this resulted from Active Pass residents' noise complaints, it would be irrelevant, because a one tone pitch produces the same decibel count as a three tone. |

Scott had mentioned in another thread that if this resulted from Active Pass residents' noise complaints, it would be irrelevant, because a one tone pitch produces the same decibel count as a three tone. The above is not correct. If sound source 1 has a volume of 100 dB and sound source 2 also has a volume of 100 dB then both sound sources together have a volume of 103 dB. With a third source of the same volume the combined volume for all 3 sources will be about 104.5 dB. To the human ear all 3 sources operating together will be perceptible as marginally louder than just a single source. The human ear is not an accurate way to measure how loud sounds are; for that you need a Sound Level Meter. If there is a large difference between the volume levels of the sources then the combined volume increase will be much less. For instance if source 1 is 100 db, but sources 2 & 3 are 90 dB then all 3 sources operating simultaneously would only be about 101 dB. The dB (decibel) is a logarithmic measurement; 100 + 100 = 103 (twice as much noise). If two noise sources together produce a level of 100 dB, and then one source is shut off, the resulting level is now 97, assuming that both sources are equally loud. www.ccohs.ca/oshanswers/phys_agents/noise_basic.html |

We currently have 11 signatures. If we want to convince BCF of anything, we'll need many more than that. 100 would be a nice number. Even 65. Please sign the petition. If you don't wish you give your full name, feel free to use an initial on the last name.

If you don't wish you give your full name, feel free to use an initial on the last name. Maybe eleven names is simply an expression of the level of interest. I'd be intrigued to see how BC Ferries might react to a petition compiled online with perhaps a hundred signatures. Perhaps they'd be flattered that people were interested enough in their operations to express a preference on this issue, and they'd accommodate your request. Or maybe they would do a bit of math and conclude that what this meant was that on the occasional sailing over the course of a year there might be one or two passengers who were concerned about how the horn sounded. As for me, I can't say that I even notice if the horn is ever sounded on the route 30 sailings I take on the Coastal Inspiration. I imagine that in Active Pass the concern is sounding enough horn to warn other traffic, while not being overly loud in consideration of residents who have to hear it between 8am and 10pm every day. In any event, as Mr Horn says, there's no harm in asking, if it matters to people. |
