"http://www.hearnet.com/at_risk/risk_at_risk.shtml" says; "One way to reduce hearing damage is by paying attention to noise levels and realizing when they are too high. According to the United States Safety and Health Standards, workers should not be exposed to more than 90 dB over a period of eight hours. Most audiologists would like to see that standard modified to 85 dB. If you work in a noisy environment, check out the decibel level you are being exposed to and take the proper precautions. Have your hearing evaluated at least once a year by a hearing health professional. Turn down the volume, or remove yourself from the noise area when possible." 92 is pretty close to 90. |

I have been looking at installing a SUB under the passengers seat of my new car. A quick survey has discovered that most commercial subs are kind of vase shaped, and will *not* fit under any circumstances. In the garage, I have a 10" subwoffer I purchased a while ago for an instrument amplifier. It is much thinner than the subs I am seeing now, so it should fit. What actually worries me is that the Sound Pressure Levels (SPL) that kids today are exposing themselves to are actually quite scary. I did a quick test the other morning (as one does), and discovered that the audio system is comfortably loud at 92db, and uncomfortable at 98db. I have read of 'soundoffs' where they measure 127db +++..... What did yor say... I cant quite hear you..... he? Protect your hearing, it wont come back. Now, to do the research to ses if 92db is likely to damage my already damaged hearing further. |

I am very carefull when blogging not to blog about every aspect of my life. As a person who used to employ people, I used to use information obtained from blog searches to decide whether to employ or not. [ You get a real insight into somebody, who at 10am is posting on his blog that his employer is an ^%^## and how he thinks that his job is crap] In this particular case, as a thoughtful individual, I make an exception... Those who know me know that I used to work for a Managed Services Provider (MSSP) here in Australia. It was a job that was fun and rewarding, until the management started to do strange things (like fail to pay super, and be tardy with the monthly pays.....) Today I learnt from a friend of a friend or a friend, (the grapevine) that the person who took my job when I left had to be paid 30% more than me.... I never thought of asking for that kind of raise... This is a simple case of do the right thing, and keep costs down, or screw up, and increase costs. I believe that employment satisfaction is not about your raw salary, but about the quality of the workinhg environment. I am with a new employer now (at a pay rise again), doing work that I enjoy, and leaving the ofice at between 4 and 5 pm every day. I also rarely work weekends. Kinda makes you feel loved.... Looking back, the cut and thrust of solving the worlds problems at 3am went past it's use by date. So, in summary, for all employers out there, look after your employees, and your corporate knowledge wont walk out the door. (It was kind of nice resigning, and saying "no amount of money wont keep me here, it is about the quality of the employer...") I could hear the fuming in the silence. By the way, Chris, I really hope that you enjoy the discussions with the officials who are chasing you. |

Wo Hoo. I got a new Mazda 3 recently, and have dicsovered all sorts of interesting things I can do with it's electrical system. So far, I have added an ambient temp sensor to a socket behind the bumper bar. Now, the car tells me what the temp outside is (8 deg C). The trick to that was the the manafacturer was very carefull to put a blanking plug into the socket, so it looked like the part I purchased wouldn't fit  . I have also modified the radio so I have an AUX input. I plan to document the protocol that the modular radio talks so that I can do a propper AUX module. ( I know that they are available commercially) What gets my goat up is that in another forum, somebody was being helpfull, then went silent - with a post saying that any further information will affect the comercial vaibility of their product....) Hopefully, I can determine the protocol data required to put text onto the display, not simply say "TAPE" when the AUX module is used. Finally, the car has a CAN bus. This means that there is lots of scope for adding a car computer to calculate MPG, etc... Yes, I know that I could have spent $10K more when I puurchased the car, but thats not the point... |
