Doubts About the Role of Rehearsal in the Irrelevant Sound Effect

The irrelevant sound effect (ISE) describes the disruption of processes involved in maintaining information in working memory (WM) when irrelevant noise is present in the environment. While some posit that the ISE arises due to split obligation of attention to the irrelevant sound and the to-be-remembered information, others have argued that background noise corrupts the order of information within WM. Support for the latter position comes from research showing that the ISE appears to be most robust in tasks that emphasize ordered maintenance by a serial rehearsal strategy, and diminished when rehearsal is discouraged or precluded by task characteristics. This prior work confounds the demand for seriation with rehearsal. Thus, the present study aims to disentangle ordered maintenance from a rehearsal strategy by using a running memory span task that requires ordered output but obviates the utility of rehearsal. Across four experiments, we find a significant ISE that persists under conditions that should discourage the use of rehearsal and among individuals who self-report use of alternative strategies. These findings indicate that rehearsal is not necessary to produce an ISE in a serial recall task and thus fail to corroborate accounts of the ISE that emphasize the involvement of rehearsal.

An investigation on cutting sound effect on power consumption and surface roughness in CBN tool-assisted hard turning

In machining activities, sound emission is one of the key factors toward the operator's health and safety. Sound generation during cutting is the outcome of the interaction between tool and work. The intensity of sound greatly influences the cutting power consumption and surface finish obtained during machining. Therefore, the current work emphasized the analysis of sound emission, power consumption, and surface roughness in hard turning of AISI 4340 steel using a CBN tool which was rarely found in the literature. Response surface methodology (RSM) and artificial neural network (ANN) techniques were utilized to formulate the model for each response. The results indicated that the maximum value of input parameters exhibited the highest level of sound due to the creation of vibration in the machine and tool. Higher sound level indicates the generation of lower power consumption but at the same instant surface roughness was leading with increment in sound level. The feed rate exhibited the utmost noteworthy consequence on surface quality with 87.71% contribution. The cutting power can be decreased by choosing the high level of cutting parameters. The RSM and ANN have a good correlation with experimental data, but the accuracy of the ANN is better than the RSM.

"The answer is blowin' in the wind" - case study of a perforated roof screen

A recently-completed building was fitted with a roof screen fabricated from perforated sheet metal panels having "U"-shaped upturned flanges. When wind impinges on the panels, complex tone clusters are generated, leading to complaints from the occupants. The unusual character of the tonal spectrum is reminiscent of a film sound effect intended to simulate a hovering extraterrestrial spacecraft. After some preliminary (but inconclusive) field investigations, it was decided to test samples of the perforated panel in a large commercial wind tunnel where the speed and angle of the airstream could be controlled. Tones generated in the tunnel were found to occur in groups or clusters - these are most pronounced when the airstream's angle of incidence is close to grazing. Gradually increasing airspeed caused the frequency of the tones to "jump" from one cluster to the next higher cluster. The physical principles of the tone-generating mechanism are not fully understood; however, it appears that structural resonances in the panel flanges are excited by air flowing over the perforate. Some form of a positive structural-acoustical feedback loop is involved since a) the frequencies within each tone cluster are quite stable and, b) damping the panel flanges extinguishes the tones.

PENERAPAN AUDIO MUROTTAL AL-QUR’AN DALAM PEMBELAJARAN UNTUK MENINGKATKAN KOMUNIKASI VERBAL PADA ANAK USIA 3-5 TAHUN DI TAUD SAHABAT QURANI

Background : Speech disorders are one of the problems that are often found in children. According to the National Center for Health Statistics (NCHS), based on parents' reports (outside of hearing loss and cleft palate), the incidence of disorders is 0.9% in children under the age of 5 years, and 1.94% at the age of 5- For 14 years, the need for managing disorders of children's verbal communication can be done with a variety of therapies, one of which is Murottal Al-Qur'an therapy. Murottal Al-Qur’an provides sound effect received by the ear and system and then transmitted to all organs of the body. Sound affects the cells of the body that have their own vibrations and cause the cells of the body to rearrange the articles in it. Where the role here is the vagus nerve which helps regulate heart rate, respiration, speech, brings motor sensory impulses to larynx of the heart and diaphragm so that the sound effects on autistic children can improve children’s communication skills. The method used in this research is Experimental Quasy with pre and post without control research design. Sampling using purposive sampling technique, in getting 10 respondents in accordance with inclusion criteria, data collection was done by using questionnaires and observation sheets, namely by using the DDST sheet (Denver Development Screening Test). Observations were made before and after Murottal Al-Qur'an therapy. The collected data is then processed using the Marginal Homogenity Test P value is obtained on the DDST (Denver Development Screening Test) sheet after the Murottal Al-Qur'an therapy is 0.001. The conclusion in this study is that Murottal Al-Qur'an therapy has an effect on verbal communication of children aged 3-5 years in the SaQu (Sahabat Qur'ani) TAUD of Polewali Mandar Regency.
