AUDIOL 715 : Physics and Acoustics for Audiology

Medical and Health Sciences

2024 Semester One (1243) (15 POINTS)

Course Prescription

The basic physics of sound; and instrumentation and the principles of digital signal processing involved in audiological research. Topics include: the physics of sound waves, room acoustics, the measurement of reverberation time; the nature of acoustic impedance; the nature of filters and amplifiers, acoustics of speech, calibration.

Course Overview

This course aims to provide students with an understanding of key concepts in physics that are relevant to audiological practice, including resonance and impedance. A strong emphasis will be placed on conceptual representation, translated into both graphical and mathematical representations. The sessions will be highly interactive and will include practical class activities to support learning.

  2. Analyse and describe complex waveforms and the nature of resonance (Capability 3.1, 4.1 and 4.2)
  3. Describe the role of each of the components that make up audio systems and explain how they work together to modify sound (Capability 3.1, 4.1 and 4.2)
  4. Quantify sound based on pressure, intensity and power using both linear and logarithmic scales (Capability 4.1, 5.1 and 5.2)
  5. Analyse the nature of sound propagation and implications for room acoustics (Capability 3.1, 4.1 and 4.2)
  6. Calculate noise dose for both occupational and recreation settings and understand the implications of the 'equal energy hypothesis' (Capability 3.1, 4.1, 4.2, 5.1 and 6.1)
  7. Describe acoustic features of speech- vowels and consonants in isolation and connected discourse. (Capability 3.1, 3.2, 4.1 and 4.2)
  8. Describe and explain why speech acoustics are important for signal processing of hearing aids and cochlear implants (Capability 3.1, 3.2, 4.1, 4.2, 5.1, 5.2 and 6.1)
  9. Describe the role of sampling, signal averaging and filtering in the digital signal processing of sound. (Capability 3.1, 4.1 and 4.2)
  10. Demonstrate an understanding of the stimuli used in the acquisition of auditory evoked potentials and methods to improve the signal to noise ratio. (Capability 4.1, 4.2 and 5.1)

Workload Expectations

This course is a standard 15-point course. Students are expected to spend approximately 10 hours per week involved in each 15-point course that they are enrolled in.

For this course, you can expect about 2 hours of interactive lectures with short problem-solving sessions interwoven, 4 hours of reading and revision of the content outside of class time, and 4 hours of work on assignments and  test preparation.

Delivery Mode

Campus Experience

Attendance is expected at scheduled activities including labs/tutorials to complete components of the course.
Lectures will be available as recordings. Other learning activities including tutorials/labs will be available as recordings.
The course will include live online events including group discussions/tutorials.
Attendance on campus is required for the test/exam.
The activities for the course are scheduled as a standard weekly timetable.

Learning Resources

Course materials are made available in a learning and collaboration tool called Canvas which also includes reading lists and lecture recordings (where available).

Please remember that the recording of any class on a personal device requires the permission of the instructor.

Student Feedback

At the end of every semester students will be invited to give feedback on the course and teaching through a tool called SET or Qualtrics. The lecturers and course co-ordinators will consider all feedback and respond with summaries and actions.

Your feedback helps teachers to improve the course and its delivery for future students.

Class Representatives in each class can take feedback to the department and faculty staff-student consultative committees.

The instructions for the practical assignment have been improved, feedback from the students suggested they were confused about some aspects of the assignment.

Academic Integrity

The University of Auckland will not tolerate cheating, or assisting others to cheat, and views cheating in coursework as a serious academic offence. The work that a student submits for grading must be the student's own work, reflecting their learning. Where work from other sources is used, it must be properly acknowledged and referenced. This requirement also applies to sources on the internet. A student's assessed work may be reviewed for potential plagiarism or other forms of academic misconduct, using computerised detection mechanisms.

Class Representatives

Class representatives are students tasked with representing student issues to departments, faculties, and the wider university. If you have a complaint about this course, please contact your class rep who will know how to raise it in the right channels. See your departmental noticeboard for contact details for your class reps.

Inclusive Learning

All students are asked to discuss any impairment related requirements privately, face to face and/or in written form with the course coordinator, lecturer or tutor.

Student Disability Services also provides support for students with a wide range of impairments, both visible and invisible, to succeed and excel at the University. For more information and contact details, please visit the Student Disability Services’ website http://disability.auckland.ac.nz

Special Circumstances

If your ability to complete assessed coursework is affected by illness or other personal circumstances outside of your control, contact a member of teaching staff as soon as possible before the assessment is due.

If your personal circumstances significantly affect your performance, or preparation, for an exam or eligible written test, refer to the University’s aegrotat or compassionate consideration page https://www.auckland.ac.nz/en/students/academic-information/exams-and-final-results/during-exams/aegrotat-and-compassionate-consideration.html.

This should be done as soon as possible and no later than seven days after the affected test or exam date.

Learning Continuity

In the event of an unexpected disruption, we undertake to maintain the continuity and standard of teaching and learning in all your courses throughout the year. If there are unexpected disruptions the University has contingency plans to ensure that access to your course continues and course assessment continues to meet the principles of the University’s assessment policy. Some adjustments may need to be made in emergencies. You will be kept fully informed by your course co-ordinator/director, and if disruption occurs you should refer to the university website for information about how to proceed.

The delivery mode may change depending on COVID restrictions. Any changes will be communicated through Canvas.

Student Charter and Responsibilities

The Student Charter assumes and acknowledges that students are active participants in the learning process and that they have responsibilities to the institution and the international community of scholars. The University expects that students will act at all times in a way that demonstrates respect for the rights of other students and staff so that the learning environment is both safe and productive.
