So it only occur at night, my room is on the left side and my dad room is on the rightAt night, only my room can feel and heard the vibrationMy dad room feel nothingHome come the vibration only occur in my room? Out of 4 room, only my room vibrateAnd it only occur at nightThe vibration noise is like a car noise like a race carConstantly runningThe vibration occur around 12 A.M and stop at 8 A.MWhere is this vibration coming from? And no, there is no car park around my house when this happen.
NoIt would be dangerous and probably mess up a few hitters swings The HR Derby is more than amazing the way it is.
The HRD already lasts too longGive those guys aluminum bats, and they'd still be hitting when the sun came up the next morning.
YesIt would make home runs go alot farther and would be very interesting to watchHowever, it would also be very dangerous for the players to use aluminum bats as wellI don't think you will ever see them using aluminum bats at the Home Run Derby.
No wayThe Derby might by no capacity end, records may be shattered, and aluminum bats are not a potential decision for MLBought to you think of somebody like Josh Hamilton (i understand he's not in it, yet.) staying up for a complete hour hitting 50 to 60 pitches and that being interior the 1st around? that they had drop from fatiquethis is not any longer a sturdy thought.
Your room is resonating with a low frequency sourceTo understand resonance, put some water into a tall glass and tap the side with a butter knife to produce a soundNotice that when you change the amount of water, the pitch of the sound changesThere is a low frequency traveling wave coming from an unknown source that is reinforced when it travels past your roomThe size and shape of your room is just right and therefor amplifies the soundIt works kind of like the cavity or resonator on a stringed instrumentIf the traveling wave is local, it could be coming from the compressor of a refrigerator or freezer perhaps located in the basementIf distant, it could be a low frequency traveling wave from an idling truck or railroad engineWe have one in our area that comes from a grain elevator generated by multiple cooling fans that are not synchronizedSuch low frequency sources can often be extremely difficult to locate because of the distance relationshipWhen you go outside, your distance as compared to your room changes and you may be in a peak location or null locationYou might be able to break up the resonance by rearranging the room furniture or by adding thick carpet or drapes since you can't move your room closer for further away from the traveling wave's peak and null pointsTo help you understand, I suggest your google sine waves with respect to peak and null points.
