Welcome

The York student section of the Audio Engineering Society


The Audio Engineering Society draws its membership from amongst engineers, scientists, manufacturers and other organisations and individuals with an interest or involvement in the professional audio industry. The AES is the only professional society devoted exclusively to audio technology. Its membership of leading engineers, scientists and other authorities has increased dramatically throughout the world, greatly boosting the society's stature and that of its members.

The AES at the University of York was the UK's first AES student section.



NEWS

CONGRATULATIONS JAMES AND DEAN!

Congratulations to winners of the 2012 York AES Section Recording Competition, James Soteriou (1st prize), and Dean O'Brien (2nd prize). James and Dean are pictured here with the section chair Adam Stringer and head of the University's electronics department, Prof. David Howard. As you can see from their delighted faces, it was well worth the effort! Particularly for James who, as well as receiving a snazzy new Audio Technica microphone, also received a subsidy from the department which enabled him to attend the AES Convention in Budapest. Well done guys! And a big thank you to our sponsors Audio Technica and Sound Technology who kindly donated the prizes.

JOIN THE COMMITTEE!

Following the recent committee elections held in November, the York AES Student Section is pleased to announce the appointment of its new chair, Adam Springer.

Don't worry if you missed the elections though, as there are still plenty of opportunities to get involved. In fact we are still looking to fill the following positions:

  • Vice chair
  • Secretary
  • Treasurer
  • Website administrator

This is a great opportunity for students at all stages in their studies to get involved in the AES, and will of course add value and intrigue to the CV!

Some benefits to members include the possibility of subsidised transport to the annual AES Convention, competitions, seminars and vital networking opportunities.

If you would like to put yourself forward for any of the positions above, please contact the chair directly. And don't forget - the section relies on its student volunteers to function, so the more *you* are prepared put in, the more benefits you can expect in return!

LECTURE BY CHRISTIAN HERBST

Lecture title:

Electroglottographic Wavegrams – a new tool to assess sound source properties in speech and singing

Lecture synopsis

The source of the human voice originates in the larynx. It is in most cases generated by the vibrating vocal folds. In this presentation, a new method for visualization and analysis of the electroglottographic (EGG) signal (i.e. a physiological correlate of vocal fold vibration) is presented. This method, termed `EGG wavegram', allows to display EGG signals (and their first derivative, DEGG) across various phonations in one graph, whilst retaining the original appearance of the unaltered waveform. The EGG signal is decomposed into consecutive individual cycles, each of which is normalized in both duration and amplitude, and is displayed on the y-axis, going from bottom to top. Overall time is shown on the x-axis. In a DEGG wavegram, the first derivative of the EGG signal is used as the input signal. In such a display, the contacting and de-contacting phases for each glottal cycle are approximated by (a) one or more dark horizontal line(s) at the lower end of the graph (contacting phase), and (b) one or more light horizontal line(s) in the upper section of the graph (de-contacting phase). Much like in a sound spectrogram, information on vibratory behavior developing in time is compacted into one single graph, thus providing insight into changes of vocal fold dynamics. As such, the wavegram allows intuitive assessment of the time-varying contact phase of phonation over a longer period of time, indicating physiological changes of laryngeal configuration, such as vocal register. EGG wavegrams promise to be useful in research, clinical diagnostics, voice therapy and voice pedagogy.

The speaker:

Christian T. Herbst, born 1970, is an Austrian biophysicist and voice pedagogue. He graduated from the University Mozarteum Salzburg. He worked as a voice teacher for the Salzburg Cathedral Boys Choir, the federal music school of Salzburg, and the Tölzer Knabenchor, Munich. Since 2009, Christian Herbst is a member of the Laboratory of Bioacoustics, Department of Cognitive Biology, University of Vienna. The scientific work of Christian Herbst is concerned with sound production in mammals, with a special focus on the physiology of the singing voice. He published several papers on laryngeal configurations and electroglottography. He is currently defending his doctoral dissertation “Investigation of glottal configurations in singing” at the Department of Biophysics, University of Olomouc.
