Abstract. During a sperm whale stranding at Rømø, the Wadden Sea, Denmark, on 4 December 1997, we were notified in time to start acoustic transmission measurements in the spermaceti complex 1 h after the specimen was seen alive. Frequency-modulated sound pulses, sweeping from 30 kHz to 10 kHz in 25 ms, were injected at the frontal surface at two positions: at the distal sac, and at the center of the junk (a compartmentalized structure below the spermaceti organ). A hydrophone next to the… 
Sound transmission in the spermaceti complex of a recently expired sperm whale calf
Sound pulses were projected into the forehead of a neonate, female sperm whale that died following a stranding and attempts to revive it. Two hydrophones, held against the skin, recorded the sound
An acoustic valve within the nose of sperm whales Physeter macrocephalus
This interpretation of the right nasal passage as an adaptive acoustic valve elucidates why the spermaceti organ and the junk are separated from each other by an air-filled space of variable volume crossing the sound path of the bent acoustic horn' in the posterior part of the nasal complex.
Sperm whale recordings collected in the Mediterranean Sea with a towed array and digital tags were used to describe the temporal and spectral characteristics of trumpets, a series of repeated units made of an amplitude modulated tonal waveform with a complex harmonic structure.
Off-axis effects on the multi-pulse structure of sperm whale coda clicks.
Coda clicks recorded close to the whale's acoustic axis showed well-defined multi-pulsed waveforms, while those recorded off-axis did not, which suggests that sound energy radiates directly into the water upon reflection off the frontal sac.
Off-axis effects on the multipulse structure of sperm whale usual clicks with implications for sound production.
It is shown that a geometric model based on the bent horn theory for sound production can explain the varying off-axis multipulse structure of sperm whales and the junk of the sperm whale nasal complex is both anatomically and functionally homologous to the melon of smaller toothed whales.
The monopulsed nature of sperm whale clicks.
On-axis click properties support previous work proposing the nose of sperm whales to operate as a generator of sound.
Sound production in neonate sperm whales (L)
It is demonstrated that sperm whale clicks are produced at the anterior placed monkey lips, thereby substantiating a key point in the modified Norris and Harvey theory and supporting the unifying theory of sound production in odontocetes.
The nose of the sperm whale: overviews of functional design, structural homologies and evolution
Comparison of nasal structures in sperm whales and other toothed whales reveals that the existing air sac system as well as the fat bodies and the musculature have the same topographical relations and thus may be homologous in all toOThed whales (Odontoceti).

Measuring Sperm whales via Acoustics and Photogrammetry
The most common vocalisations heard from sperm whales are short, broadband clicks which often display a decaying, evenly spaced, multi-pulse structure. The time between these pulses (inter-pulse
