- Abstract: Provides acoustical background necessary to understand the role of sound in speech communication. Analyzes constraints imposed by the properties of sound and human anatomy on speech production (sound production from airflow and filtering by the vocal tract); auditory physiology (transformation of acoustical waves in the air to mechanical vibrations of cochlear structures); and sound perception (spatial hearing, masking, and auditory frequency selectivity). The Acoustics of Speech and Hearing is an H-Level graduate course that reviews the physical processes involved in the production, propagation and reception of human speech. Particular attention is paid to how the acoustics and mechanics of the speech and auditory system define what sounds we are capable of producing and what sounds we can sense. Areas of discussion include: 1. the acoustic cues used in determining the direction of a sound source, 2. the acoustic and mechanical mechanisms involved in speech production and 3. the acoustic and mechanical mechanism used to transduce and analyze sounds in the ear

- Abstract: Take a hands-on ride through the fundamentals of electronics and acoustics, and the process of loudspeaker design and construction. Learn about the engineering and art involved throughout music/movie recording and playback, the design and application of everything from microphones to DACs, amplifiers, and speakers. With the aid of computer assisted audio measuring equipment at the MIT Edgerton Center, analyze the frequency response and distortion of speaker drivers, and understand their effect on what we hear. Design your own speakers - driver selection, crossover networks, and enclosure design - and build them in class!

- Abstract: Students model and design the sound environment for a room. They analyze the sound performance of different materials that symbolize wallpaper, thick curtains, and sound-absorbing panels. Referring to the results of this analysis, they then design another room based on certain specifications and test their design.

- Abstract: The Impulse Response Measurement Toolbox is a simple, convenient, and free open-source solution for measuring impulse responses, magnitude spectra, and phase spectra of single-input, single-output (SISO) linear systems. Two impulse-response measurement methods are explained and demonstrated. The Golay code measurement technique is particularly robust to additive white noise, while the swept sine measurement technique is robust to weak nonlinearities.

- Abstract: Students design musical instruments inspired by what they learn in an experiment with beakers of different liquids. In the "research and investigate" stage of design, they experiment to determine the general relationship between pitch (frequency) and liquid density. They use their results to draw designs for instruments that can create sound at several different pitches.

- Abstract: The activities in this course are designed for children preschool or elementary school age. Some introduce basic music concepts; others focus on music of a particular culture. All encourage noise and activity, so they make excellent breaks from desk work, but be sure you are not disturbing the class down the hall!

- Abstract: The Sound and Light unit provides students with an understanding of sound and light waves through the theme of the "Sunken Treasure," a continuous story line throughout the lessons. In Lessons 1-5, students learn about sound, and in Lessons 6-10, they explore the concepts of light. The first lesson introduces the concepts of longitudinal and transverse waves. Students then move on to the concepts of wavelength and amplitude in transverse waves. In the third lesson, students learn about sound through the introduction of frequency and how it applies to musical sounds. Next, girls and boys learn all about echolocation what it is and how engineers use it to "see" things in the dark, or deep underwater. The last of the five sound lessons introduces acoustics, in which students learn how different materials reflect and absorb sound.

- Abstract: Students explore the sound dampening ability of numerous materials by designing and prototyping model sound booths. As a result, students learn about how sound is reflected, absorbed and travels through various materials, thus giving them an overview of sound dampening, energy absorption and sound propagation in the context of engineering. Students also create blueprints and document their findings in a formal lab report.

- Abstract: In this lesson, students are introduced to communications engineers as people who enable long-range communication. In the lesson demonstration, students discuss the tendency of sound to diminish with distance and model this phenomenon using a slinky. Finally, Alexander Graham Bell is introduced as the inventor of the telephone and a pioneer in communications engineering.
