9015 movement for noise reduction and energy storage
Question about noisy Miyota 9015 movement
I recently acquired a Kemmner automatic with Miyota 9015 movement. I really love the watch, and generally it keeps good time (well within published specs for this movement), but I''m concerned that there may be an issue with it. The watch emits a pronounced rattling noise when the case is tapped (or otherwise jolted by a sudden movement).

Fundamentals of Noise Reduction
where P x (ω) and P v (ω) are, respectively, the power spectral densities of the signal x(n) and noise v(k), and ω is the angular frequency. Apparently, the higher the SNR value, the cleaner the signal. In the context of noise reduction, both the terms a priori SNR and a posteriori SNR are often used. The former usually refers to the SNR of the observed noisy signal, a

What is a 9015 caliber?
The caliber 9015, which was presented for the first time in 2009, is a revolutionary development of the 8215 caliber. Equipped with a ball bearing rotor, a second stop and a date with a quick-change circuit, this new plant works very precisely with 28,800 half oscillations per hour.
What is a Bess sound barrier?
BESS providers also have the option to utilize sound barriers, which can be physical or natural (i.e., concrete or dense trees), to limit the direct transmission of noise to nearby surrounding areas.
Do power conversion devices emit continuous humming noise?
Power conversion devices in BESS, like inverters, which transform direct current (DC) to alternating current (AC) for grid integration, also emit continuous humming noise. Efficient conversion processes require stable operating temperatures, increasing the need for effective, but noisy, cooling solutions.
