ONLINE COURSE – Ecoacoustic Data Analysis (ECAC01) This course will be delivered live
6th July 2020 - 10th July 2020
This course will now be delivered live by video link in light of travel restrictions due to the COVID-19 (Coronavirus) outbreak.
This is a ‘LIVE COURSE’ – the instructor will be delivering lectures and coaching attendees through the accompanying computer practical’s via video link, a good internet connection is essential.
TIME ZONE – UK local time (GMT+0) – however all sessions will be recorded and made available allowing attendees from different time zones to follow a day behind with an additional 1/2 days support after the official course finish date (please email email@example.com for full details or to discuss how we can accommodate you).
This course will introduce and explain the different applications for bioacoustics to answer ecological questions. Starting with a detailed overview of the correct and most efficient methods of data collecting in the field, this course will then go on to show delegates cutting edge methods for analysing and interpreting different types of bioacoustic data.
By the end of this 5-day practical course, attendees will have the capacity to set up and deploy recording devices, download acoustic data, how to analyse this data and report the results.
Bioacoustic methods are becoming increasingly recognised as a valuable approach for ecological surveying. Bioacoustics can be used to effectively replace some current techniques whilst increasing the quality of the data collected or can be used in unison to compliment them. They are particularly useful for developing long-term, permanent datasets that can be independently reviewed, particularly for rare species with low detectability, or when working in difficult environments.
The course will provide a practical introduction to bioacoustics methods, with a mix of lectures and practical workshops, and some optional fieldwork. It will start with a basic introduction to sound and recording theory, before developing hands-on skills in setting-up and deploying a range of acoustic and ultrasonic audio recorders. Workshops will then cover the download and analysis of audio data, mainly using Kaleidoscope Pro and Audacity software. The processed audio data will then be analysed and presented using R, the free software environment for statistical computing and graphics (http://www.r-project.org/).
Example data sets will mostly cover applications for bat and bird surveys, as well as the use of Acoustic Indices as biodiversity metrics. If you are working in different areas of ecology using bioacoustics please feel free to contact firstname.lastname@example.org so we can advise if the learning outcomes are transferable to your field of research.
This course is suitable for anyone working with bioacoustics from those in academia, conservation biologists and persons in industry and government.

Dr. Carlos Abrahams
There will be morning lectures based on the modules outlined in the course timetable. In the afternoon there will be practicals based on the topics covered that morning. Data sets for computer practicals will be provided by the instructors, but participants are welcome to bring their own data.
Assumed quantitative knowledge
A basic understanding of statistical concepts. Specifically, generalised linear regression models, statistical significance, hypothesis testing.
Assumed computer background
Familiarity with R. Ability to import/export data, manipulate data frames, fit basic statistical models & generate simple exploratory and diagnostic plots.
Equipment and software requirements
A laptop/personal computer with a working version or R and RStudio installed. R and RStudio are supported by both PC and MAC and can be downloaded for free by following these links.
It is essential that you come with all necessary software and packages already installed (you will be sent a list of packages prior to the course) internet access may not always be available.
