Word frequency is known to have various effects (Brysbaert et al. 2011; Rudell 1993). Memorization is positively affected by higher word frequency, likely because the learner is subject to more exposures (Laufer 1997). Lexical access is positively influenced by high word frequency, a phenomenon called word frequency effect (Segui et al.).
In several studies, participants read a list of high or low frequency words along with nonwords (or pseudowords). They were tasked with pronouncing the words or nonwords as fast as possible. [10] High frequency words were read aloud faster than low frequency words. [10] Participants read the nonwords the slowest.
For example, the interference of two pitches can often be heard as a repetitive variation in the volume of the tone. This amplitude modulation occurs with a frequency equal to the difference in frequencies of the two tones and is known as beating. The semitone scale used in Western musical notation is not a linear frequency scale but logarithmic.
List-length effect: A smaller percentage of items are remembered in a longer list, but as the length of the list increases, the absolute number of items remembered increases as well. [163] Memory inhibition: Being shown some items from a list makes it harder to retrieve the other items (e.g., Slamecka, 1968). Misinformation effect
Another example is the word "said". It breaks the phonetic rule that ai normally makes the long a sound, ay. In this word it makes the short e sound of eh. [9] The word "said" is pronounced as /s/ /e/ /d/. The word "has" also breaks the phonetic rule of s normally making the sss sound, in this word the s makes the z sound, /z/."
High frequency hair cells would therefore be sensitive to a greater proportion of the total energy in noise than low frequency hair cells. Though hair-cell responses are not exactly constant Q, and matters are further complicated by the way in which the brain integrates adjacent hair-cell outputs, the resultant effect appears roughly as a tilt ...
The horizontal axis shows frequency in Hertz. In acoustics, loudness is the subjective perception of sound pressure.More formally, it is defined as the "attribute of auditory sensation in terms of which sounds can be ordered on a scale extending from quiet to loud". [1]
It is a common understanding in psychoacoustics that the ear cannot respond to sounds at such high frequency via an air-conduction pathway, so one question that this research raised was: does the hypersonic effect occur via the "ordinary" route of sound travelling through the air passage in the ear, or in some other way?
