How Decibels Apply to Music and Sound. In music, decibels are a measurement of Sound Pressure Level (SPL). When we say the speakers at a rock concert are playing at 110dB, what we really mean is that theyâre playing at 110dB SPL. Since the decibel is only a ratio, 110dB is actually a comparison to a different number: 0 SPL.
The frequency range of a musical instrument is called ambitus. The Frequency Range of a CATV amplifier are categorised as mentioned below; 1  Low Frequency Range are 1&nbsp;Hz to 150&nbsp;MHz. 2  Intermediate Frequency Range are 151&nbsp;MHz to 299&nbsp;MHz.  High Frequency Range are 300&nbsp;MHz to 50&nbsp;GHz.
