bass is always omnidirectional. there is no exception to that. and yes, like normal people, there has been plenty of times that i hear a loud system, and look into a crowd of cars and have a difficult time telling which one it is. hmm... maybe im just weird? the only way u can tell where its coming from, is when the volume gradually increases as it gets closer, peaks in volume, and then gradually decreases as it gets farther away. other than that, bass has been and will always be dubbed omnidirectional. Well , I have to dissagree ! frequencies shift as you are moving away or towards something , in short : to the person standig/sitting stil the sound shifts .you produce higher frequencies when you drive towards them as the sound is compressed and lower as the soundwaves are elongated as you move away from him . same goes for SPL ,the closer the person is to you it louder it wil be. this way even bass frequencies can be detected easily from which direction they come from . so low frequency waves themselves are omnidirectional you in your car are NOT The phase will change yes, but frequency no. OP: You were being loud, breaking the law (whether you agree with it or not), was mouthing off to the cop (never a good idea), and were most likely being an ass. I don't feel sorry for you. Also, if you type a little more legibility it would make everyone elses life easier if they care to try to read your posts. It may just be the internet but you never know if it is going to come back and bite you in the ass. You don't have to type in perfect English at all, just a little bit of common punctuation and care goes a long ways.
