Although the theory is no longer consistent with experimental data, the paper itself served as a significant inspiration for studies in odontocete bioacoustics and in the experimental approach to testing the hypothesis a number of significant findings were made, including the loudest sound pressures ever measured from any animal (from sperm whales); the first odontocete feeding sounds recorded in the wild (narwhals); first experimental evidence for the sound transmission pathway in the sperm whale nose; and the hyperdirectionality of the sperm whale echolocation sound beam.
