An acoustic filter for helical springs by immersing the first turn in a viscous medium |
摘要 |
Device for filtering out the acoustic frequencies in suspensions using coil springs by immersing the first turn of the spring in a viscous medium. This device thus supplements the filtering power of the helical spring above and beyond the frequency range (bandwidth) for which it was dimensioned. <IMAGE>
