|HMS II.6 is an Artificial
Head Measurement System which is equipped with free-field
microphones instead of IEC-711 ear simulators. It is therefore
especially suited for measurements of sound sources far
from the ear (e.g. hands-free terminals) in sending and

is a cost-effective alternative to HMS II.3.
However, HMS II.6 is not suited for measurements of sound
sources close to the ear (such as headphones, headsets,
