Audiometric Headphone

Please click here for more information about Tesla Technology.Completely re-engineered transducers (drivers) based on a neodymium ring magnet with optimized magnetic field characteristics. This combination creates a magnetic field inside the transducer which is far stronger (> 1,2 Tesla - measuring unit for magnetic flux density - with current headphones the strength of the magnetic field is < 0,65 Tesla) than in standard headphones. Because of this increased magnetic field, the voice coil is more compact but still provides a very high degree of efficiency. The membrane, consisting of a 3 layer "compound foil", delivers an extremely precise frequency response and guarantees, in collaboration with the strong magnet, a transparent and distortion free sound.

▲ Supraaural, lightweight and robust design 
Tesla Technology with highest efficiency 
▲ Perfect for aural-acoustical measurements
▲ Colour coded right/left designation: red / blue
▲ Excellent attenuation of ambient noise
▲ Flexible split headband 
▲ 90° swivelling earcups 
▲ Single-sided cable 
▲ Large Soft-Skin earpads and headband for good wearer comfort 
▲ Packed in bubble bag

The AT 1350 A is a closed, dynamic headphone for the use with audiometers. It is used for aural-acoustic investigations and measurements. Due to the closed design of the headphone, ambient noise inefficiently attenuated. The efficient Tesla transducers ensure every good reproduction of the measured results. The right/left identification with coloured rings meets the standards.The comfortable, replaceable ear pads and the flexible headband ensure ultimate comfort and an absolutely secure fit. The pivoting ear cups (90°) allow listening with one ear. The single-sided, straight connecting cable comes with bare ends.

technical data

Transmission type   Wired
Headphone design (operating principle)   Closed
Headphone impedanceAlso known as nominal impedance. The impedance is the AC resistance of the coils of loudspeakers and headphones in ohms. Since impedance depends on the frequency, it is always specified at a frequency of one kilohertz.   32 ohms
Headphone frequency responseThe frequency response specifies the highest and lowest frequencies reproduced by the acoustic transducer of the headphones.   5 - 30.000 Hz
Nominal sound pressure levelThe acoustical level, the headphone transducer produces to an artificial ear (a measurement device, which simulates a human ear) with an input power of 1 mW (dB/mW @ 500 Hz).   125 dB
ConstructionSound coupling to the ear. A differentiation is made between supraaural headphones, circumaural headphones and in-ear headphones.   Supraaural (on-ear)
Cable & plug   Open ends (no plug)
Net weight without packaging   214 g
