Instructional Plans: Grades 9–12

Instructional Plans ◽

Instructional plans consist of planning necessities, standard alignment, alignment to philosophies approached in earlier chapters, as well as instructional procedures and assessments. Adaptations for other grade-level bands as well as potential extensions are available for each plan. This chapter includes the following instructional plans: Audio Engineering: Ratios in Recording, Designing a Chromatic PVC Instrument, Controlled Voltage: Composing, Performing, and Improvising with Subtractive Electronic Synthesis, and Sound Pollution and Its Effects on Local Bird Ecology. In Audio Engineering: Ratios in Recording, students will use a method of measuring and experimentation to maximize the sound quality of a given recording environment. In Designing a Chromatic PVC Instrument, students will design a one octave chromatic instrument using mathematical calculations and representations to create initial expressive statements and explain the relationships among the frequency, wavelength, and speed of waves traveling in the PVC pipes. In Controlled Voltage: Composing, Performing, and Improvising with Subtractive Electronic Synthesis, students will interface with the subtractive architecture of electronic instruments, the concept of controlled voltage, and the function of an electronic sequencer. In Sound Pollution and Its Effects on Local Bird Ecology, students will learn about modern sound pollution and the effect it has on many different forms of ecology. Students will determine at the end of their own study whether or not there were any observed correlations between these datas captured, and if other data could be used to claim causation.

Gender System

Abstract We re-assess the gender system of Ogbe-Oloma, an Edoid village variety of Nigeria. System exponents are prefixes that define form class and reflect grammatical number. We find that eight agreement classes undergird fourteen genders, while seventeen nominal form classes frame twenty-five number inflections. Prefix mapping from inflection to gender is non-isomorphic. Mapping is however constrained by syllable shape, CV- versus V-, and alliterative sound quality of prefix consonant, not vowel. In addition, several number inflections trigger agreement in multiple genders leading to one gender that exclusively refers to nouns with human reference.

This paper aims to identify the attributes that describe aircraft interior noise, determine most important psychoacoustic models that characterize cabin sounds, and construct a prediction model that can be utilized for VIP and business jets to evaluate subjective perception. In the first part, paired comparison listening tests and free verbalization are conducted with expert subjects who experienced VIP and business aircraft flight. The study generated a list of adjective pairs that describe perception of cabin sounds to be used for semantic differential listening tests. Multi-dimensional scaling is performed on paired comparison data. Results showed that subjects’ decisions can be categorized in loudness and annoyance dimensions which are not necessarily linearly associated. The second part of the study is the development of a sound quality prediction model for aircraft cabin. Semantic differential tests are conducted with potential customers. Objective sound quality metrics are correlated to subjective test responses using principal components regression. This model is found to be most effective explaining pleasantness, comfort, and loudness perception. It is intended to be utilized to modify/redesign noise control treatments and sound signature of an aircraft. All listening tests were conducted inside an aircraft cabin simulator considering the influence of visual content.

The University

Fans are main components e.g. in heating, ventilating and air conditioning systems for vehicles or buildings, cooling units of engines and electronic circuits, and household appliances such as kitchen exhaust hoods or vacuum cleaners. End-users increasingly demand a high sound quality of their system or device. The overall objective of a recent research project at the University of Siegen is a multidimensional assessment of fan sound quality. In a first step an advanced novel semantic differential for the assessment of fan-related sounds is established with the aid of carefully designed jury tests. Eventually, this semantic differential is employed for sound quality jury tests of fans in kitchen exhaust hoods, heat pumps and air purifiers as a first case. Finally, a prediction model is suggested, which relates the outcome from the jury tests to objective metrics. A principal component analysis is carried out and yields five main assessment criteria with 23 relevant adjective scales. The results show that the perceived sound quality of fan systems is mainly determined by the loudness and tonality of the sound. The spectral content (represented by the sharpness) as well as the time structure (represented by the roughness) have no significant impact on perceived sound quality of the fan systems investigated.

Design Variables

A Vibro-Acoustic Finite Element Method (FEM) model capable of calculating the transient sound pressure generated by the door slam of a vehicle was developed in this study. A design sensitivity analysis (DSA) was performed for investigating the effects of major design variables on the related sound quality metrics. The methodology was developed using a sedan-car and its FEM model. This paper shows that a Computer Aided Engineering (CAE) model can be used as a rather powerful tool for giving design change decisions for the door components from sound quality point of view during vehicle body development according to psychoacoustic parameters.
