Background: Individual differences in morphometric and somatoscopic observations of pinna of ear were studied to explore the potential of pinna of ear as a biometric tool.Methods: Morphometric and somatoscopic data of right ear of 350 Indian individuals (Age: 17-25 years) was collected. Measurements of pinna length, pinna width, pinna root, pinna p...

... of ear is a cartilaginous projecting portion of the external ear. Different parts of the pinna are: Helix, antihelix, triangular fossa, scapha, tragus, antitragus, concha, and ear-lobe ( Figure 1). Many times, there is a small expansion of the helical fold at the junction of the superior and descending portions of the helix which is called Darwin tubercle. ...

Numerical simulations of head-related transfer functions (HRTFs) conventionally assume a rigid boundary condition for the pinna. The human pinna, however, is an elastic deformable body that can vibrate due to incident acoustic waves. This work investigates how sound-induced vibrations of the pinna can affect simulated HRTF magnitudes. The work will...

... Similarly, they documented the mean total ear height among South Korean males as 64.6mm compared to 60.3mm in their female counterparts, same entity was found to be similar among Italians; 61.9mm among males and 56.1mm among Italian females. Among the Germans, males were documented to have mean total ear height of 65.0mm compared to 61mm in their female 13 counterparts. Maitreye found that the probability of any two individuals having exactly same pinna generally is 0.0008%. ...
Background: Individuals with abnormal set of ears feel
depressed, and this could affect their self esteem.
Methods: A cross-sectional study that assessed auricular
anthropometric measurements of pupils at the schools for the
deaf and those in regular schools within Kaduna metropolis,
Kaduna. Ethical approval was obtained from the state Ministry
of Health. Consent was obtained from the parents/guardians
of the pupils and assent from the pupils. Pupils were selected in
a multi-staged sampling fashion. Digital Vernier Caliper was
used to measure the total ear height, the ear width and the ear
projection of the deaf pupils and normal pupils. The generated
data was analysed with SPSS version 20.
Results: Age range of subjects was 8-17 years, mean of
13.5±2.4 against 7-17 years, mean of 13.1±1.8 for controls.
Mean right total ear height among subjects was 61.5±7.2mm
against 61.3±4.6mm among controls. Left mean total ear
height among subjects and controls was 61.6±7.2mm and
61.5±4.4 respectively. Mean right ear width among subjects
and controls was 33.4±5.2mm and 37.2±4.0mm respectively.
Mean left ear width among subjects was 33.4±5.3mm and
37.2±4.1mm among controls. Mean right ear projection
among subjects was 21.7±4.1mm and 21.5±2.4mm among
controls. Mean left ear projection among subjects and controls
was 21.9±3.7mm and 21.4±2.3mm respectively.
Conclusion: Our study showed that the deaf pupils had lower
values of ear width in both ears compared to the general
population.
