The Animal Audiogram Database (AAD) provides audiogram data and metadata of auditory experiments and links to the original sources of the data in a structured and easily accessible way.

Browse, view and download audiogram data in a variety of ways. Combine audiogram data for comparative analysis based on animal details, experimental conditions, or publications.

Audiograms are an important resource for understanding the hearing abilities of animals. Audiogram data is relevant for studying animal acoustic physiology, behaviour, and ecology and likewise for assessing the effects of anthropogenic noise on wildlife and environmental stewardship.

The AAD is based on data from peer-reviewed scientific publications. The data have been manually extracted from the original sources and curated. Currently, the database focuses on audiograms of marine mammals and birds to improve our understanding of the effects of anthropogenic noise in marine environments. The database is drafted as a free and open resource whose structure and content can be extended by collaborative development for audiogram data from any taxonomic group and habitat. If you see any errors in the database, please send us an e-mail to

The WIKI is supposed to help users to use the database and find information related to hearing studies fast. It is not supposed to be a complete knowledge base, but may grow over time. Entries have been created by Michael Dähne and Adam B. Smith.


The Animal Audiogram Database was developed as part of the project Hearing in Penguins conducted at the Museum für Naturkunde Berlin funded by the German Environment Agency (UBA) with means from the Federal Ministry for the Environment, Nature Conservation and Nuclear Safety (BMU, FKZ3717182440). We thank Adam B. Smith, Magnus Wahlberg, Jakob Christensen Dalsgaard, Georg Klump, Ole Naesby Larsen and many more for comments during the creation of the database. We thank all collaborators for their help and enthusiasm!
