Egg Collection Belts: These belts run beneath the cages or nests, gently transporting the eggs to a central collection point. Egg picking device: Long service life, smooth operation, low noise, thereby reducing the impact of noise on chickens, improve egg production rate.
Sep 1, 2016 · A small battery-powered submergible vibrator designed by de Jong et al. (2017), or the "noise egg," was employed to generate continuous low-frequency noise at approximately 160 Hz. The egg was

Sep 7, 2016 · The noise egg provides a simple and inexpensive way to create low-frequency sound under water. With some adaptations to the actual research question, we suggest it could be used in a wide range of set-ups both in field and laboratory experiments.
Sep 7, 2016 · Here, we describe a device that can produce a low-frequency sound, which can be used as an experimental source of noise both in aquaria and in the field. The device is completely self-contained and costs around 10 euros per ‘noise egg’.
