(Video link HERE.) Finite element analyses were performed to model the nonlinear stiffness of the structure and the voltage output of the device. (My brother and I own the four-unit building, and I live in one of the apartments.) Consultant. Similar plant, in those apartment blocks which have central services, may be the source of the noise in these premises, but a core of low frequency noise problems remain, of unknown origin, which continue to cause considerable annoyance.

Distance to complaint was ~150 metres, but it could only be heard inside a house as the air-transferred noise was making the house wall vibrate and re-emit the noise. His thinking was that if we get readings of the vibration, we might be able to match it to some mechanical, either on the roof or in the basement, a neighbor’s apartment etc. In order to excite vibrations with ultra-low magnitude and frequency (down to 0.1 nm and 1 Hz, respectively) we used a home-made piezoelectric shaker based on two similar PZT tubes (ceramic type APC 850, APC International Ltd., Mackeyville, PA, USA), with a length of 40 mm, and inner and outer diameters of 10 and 11 mm, respectively. There's a lot of traffic noise outside though, probably masks the sound. This noise/vibration (n/v) is like a low frequency throb which I can feel when I lay in bed or sit in a chair or lean against a wall etc. The transmissibility as a function of frequency ratio is shown in Figure 3. Hi Thank you for looking at my post, I appreciate any input and am looking for some expert advice on my situation. I have owned a condo that is at the top floor of a 4-story building for 2 years now. : Low-Frequency Vibration Measurement by a Dual-Frequency DBR Fiber Laser 209 quite linear curve is observed.
