Abstract An accelerometer assembly is disclosed which includes an accelerometer mounting block formed of a rigid material having a proportion of the modulus of elasticity to the density of less than 15,000,000 psi/lb/in3. The natural frequency of the mounting block is safely below the accelerometer's response frequency but higher than the frequency to be recorded so that the mounting block does not resonate with high frequency vibrations and cause quick saturation of the accelerometer amplifier or erratic signals. The preferred mounting block is formed of polycarbonate, which is non-metallic, rigid, and lightweight, and has a natural frequency sufficiently below that of the accelerometer.
