In this study, we investigate the norm of difference operator on some sequence spaces such as Hilbert and Cesaro matrix domains. Therefore present study is a complement for those results obtained in [1].

This study investigated the role of the F0 height of the final tone in signaling the difference between Mandarin statements and echo questions. We recorded native speakers producing pairs of statements and echo questions ending in the four Mandarin tones (high, rising, low, and falling). The first two syllables of the utterances comprised pairs of high and low tones, or rising and falling tones...

In a fast fading channel, the orthogonality of the two consecutive Space Time Block Codes (STBC)-Orthogonal Frequency Division Multiplexing ( OFDM) symbols will be destroyed and the received signals cannot be perfectly separated. TR(Tone Reservation) is a technique designed to combat this problem by reserving a number of carries(tone) in the frequency domain to generate a cancellation signal in...

INTRODUCTION Long-latency auditory evoked potentials represent the cortical activity related to attention, memory, and auditory discrimination skills. Acoustic signal processing occurs differently between verbal and nonverbal stimuli, influencing the latency and amplitude patterns. OBJECTIVE To describe the latencies of the cortical potentials P1, N1, P2, N2, and P3, as well as P3 amplitude, ...

The octave illusion (D. Deutsch, 1974) occurs when 2 tones separated by an octave are alternated repeatedly, such that when the right ear receives the high tone, the left ear receives the low tone, and vice versa. Most subjects in the original study reported hearing a single tone that alternated from ear to ear, whose pitch also alternated from octave to octave, and D. Deutsch (1975a) proposed ...

Perceptual similarity between Tone 2 and Tone 3 in Mandarin was widely discussed in previous studies Moore and Jongman 1997 , Huang 2004 , Bent 2005 . Other tonal contrasts are hardly addressed. However, recent findings of Mandarin tones show that Tone 3 and Tone 4 are confusing in terms of descent slope. A big difference between previous studies and current ones is kinds of Tone 3 stimuli: pre...

background and aim: human beings receive a variety of sounds in their everyday lives. these sounds are generated by different sources, and are heard simultaneously or with a small time sequence. a characteristic of the auditory system is its ability to analyze complex sounds, and to make decisions about the source of each constituent part of these sounds. the present study intends to assess nor...

In this paper, we report on some acoustic data suggesting the existence of the Accentual Phrase (AP) in Neapolitan Italian. In late narrow focus utterances in which intonation modality was varied, there was a difference in the shape and slope of the interaccentual region linking the H target of the prenuclear rise with the L target of the following nuclear rise. We hypothesized that such differ...
