Module Title:Principles of Sound
Language of Instruction:English
Credits: 5
NFQ Level:6
Module Delivered In No Programmes
Teaching & Learning Strategies: A mixture of active learning and prescribed learning will be implemented. Prescribed learning will take the form of lectures where the student will be introduced to core concepts in sound to allow the student to develop their unistructural and multistructural knowledge in a controlled learning environment. Active learning will take the form of laboratory exercises where students will examine aspects of sound such as beat frequency, loudness (phons) curves, equalisation along with related mechanical aspects of sound such as damping and loudspeaker design. The goal of these active learning sessions in the laboratory will be to facilitate the student to be able to relate the prescribed knowledge of the lectures with real-life objects & phenomena such as speakers, beat frequency and sound filtering/equalisation. Written assignments will be used to strengthen the understanding of both the prescriptive and active learning aspects of the module.
Module Aim: The aim of this module is to allow the student the opportunity to understand difficult but fundamental ideas from Physics & acoustics with an emphasis on their practical ramifications. It is furthermore envisioned that the knowledge developed here can later be extended as it will compliment later modules, which they will undertake in their degree, that focus on microphones & other audio studio equipment.
Learning Outcomes
On successful completion of this module the learner should be able to:
LO1 Describe the properties of sound such as pitch, loudness & timbre.
LO2 Comprehend & measure sound & its properties.
LO3 Relate the properties & measurements of sound with the principles of the technologies that capture, store, process and transmit sound.
LO4 Demonstrate competency in the ability to measure and characterise sound in relation to how it is processed by the human ear and brain.
LO5 Judge & appraise important parameters of sound reproduction such as equalisation and filtering along with speaker types and ratings.
LO6 Evaluate digital & analogue sound reproduction methods.
LO7 Develop problem-solving skills broad enough to be applied in an industry where the use of technology changes rapidly.
