Comparison Between Binaural Microphones
Neumann Binaural Microphone KU 100h
The KU 100 is a human head replica
with microphones inside of the ears. It is
used for binaural pick-up to create the
most realistic stereo recordings. This
third-generation design is loudspeaker
compatible, and accurately reproduces
ambient acoustics with information about
distance, direction, and perspective. It
offers exceptional speech intelligibility in
noisy environments. Applications for the
KU 100 include radio drama, special
effects for film, outdoor nature
recordings, acoustic evaluation, and
Schoeps KFM6 Binaural Microphone
Novel, head-related stereo main microphone for
Stereo main microphones are distinguished by the
simplicity of the recording technique and of the setup:
Only two capsules and recording tracks are required,
and with the KFM 6 only one microphone cable is needed.
With the sphere microphone the interaural differences
are similar to those occurring at the human head.
The KFM 6 sphere microphone is the embodiment of a newly-
developed stereo main-microphone design using an
acoustic baffle. "Dummy head" systems are well-known
for the excellent results they can provide, but the
recordings made with such systems are suitable only for
The frequency response on the stereo main axis of the
KFM 6 is flat when measured at the output of either
channel. If a sound source moves around the sphere,
the intensity in the one channel will increase by the
same amount as it decreases in the other. This is
brought about by the unique construction of the
microphone capsules, the effect of the sphere as an
acoustic baffle, and some special electronic circuitry
built into the amplifier. As a result, the sum of the
energy from the two channels is largely independent of

ESLAB "Sphere" Binaural Microphone
Two special high quality pressure transducers are
mounted flush on the surface of a sphere 15 cm in
Such a microphone configuration would not only
provide spectral-vs-angular incidence information
but also interaural arrival-time cues, the main
difference between the ordinary Stereo Microphones
and the Binaural microphoines.
This explains why a sound image quite similar to
that for a listener at the microphone position is
obtained, with the room ambience included.
The frequency response on the main axis of the microphone in the free sound field and also the
frequency response in the diffuse sound field remains
The ESLAB "Sphere" microphone was
developed so that comparable results could be achieved
for headphones and loudspeaker playback.
Designed for Field and Concert recordings.

Core Sound's "High End Binaural" microphones
Core Sound's "High End Binaural" microphones starts with
two DPA4061s (or DPA4060s), selected so that they are
matched to within 1 dB.
For binaural recordings the cartridges are aimed
outward (not forward) much as your ears are. This copies
the human ear, ensures a true binaural pickup pattern,
and accurately captures sonic information coming from
The HEB microphones require a bias voltage.
The HEB "battery box" contains a nine volt battery and
The HEBs have a very flat and extended low frequency
response. In some cases, particularly where the hall or
sound system has an emphasized bass frequency response
("hall boom"), it is desirable to roll off the low bass
frequency response using the switchable box. It is
switched between flat response and the bass filter response very

Core Sound Binaural Microphone
Core Sound Binaural Microphones are omnidirectional and pick up
sounds in all directions more or less equally. They are
very well suited for tapers on a budget and
are a good choice for recording concerts and lectures.
The microphones are very unobtrusive. When in place,
they look like eyeglass retainers. (intended for eyeglass mounting)
The microphones themselves are amazingly small.
When the cord is routed down a shirt or sweater,
there's little evidence that you are creating a very
high fidelity recording of a sound event.
