Infant and Toddler Activities: Young Infants, Mobile Infants, and Toddlers. Because infants change and grow so quickly, curriculum must. adjust to their developmental level. For this reason, activities are. designed as prototypes for young infants, mobile infants, and.
A standing wave in a rectangular cavity resonator. A resonator is a device or system that exhibits resonance or resonant behavior, that is, it naturally oscillates at some frequencies, called its resonant frequencies, with greater amplitude than at others.esonators are used to either generate waves of specific frequencies or to select specific frequencies from a signal. Musical instruments use acoustic resonators that produce sound waves of specific tones.
Although it may look like a smaller version of a muffler, resonators are designed to be supplemented into an exhaust system to further tune the sound and not replace a muffler completely. A resonator further dampens the sound but more importantly, it is there to alleviate what is known as âexhaust droneâ. Usually during cruising speeds, some exhaust set-ups may exhibit a background buzz that may be heard even inside the passenger compartment.
