Aloha,

My co-authors and I are pleased to announce the publication of the
following paper:

Chen, J., Pack, A.A., Au, W.W.L., Stimpert, A.K. (2016) Measurements of
humpback whale song sound levels received by a calf in association with a
singer.  The Journal of the Acoustical Society of America *140*, 4010-4015;
http://doi.org/10.1121/1.4967444

Abstract:

Male humpback whales produce loud “songs” on the wintering grounds and some
sing while escorting mother–calf pairs, exposing them to near-continuous
sounds at close proximity. An Acousonde acoustic and movement recording tag
deployed on a calf off Maui, Hawaii captured sounds produced by a singing
male escort. Root-mean-square received levels ranged from 126 to 158 dB re
1 μPa. These levels represent rare direct measurements of sound to which a
newly born humpback calf may be naturally exposed by a conspecific, and may
provide a basis for informed decisions regarding anthropogenic sound levels
projected near calves.
