The auditory steady state response (ASSR) is an oscillatory brain response. which is phase locked to the rhythm of an auditory stimulus. ASSRs have been recorded in response to a wide frequency range of modulation and/or repetition. but the physiological features of the ASSRs are somewhat different depending on the modulation frequency. https://www.bekindtopets.com/save-now-Aqua-Pure-3MFF101-Full-Flow-Drinking-Water-System-Replacement-Cartridge-flash-choice/
