Oyaide NRF-005T Noise Suppression Tape
Oyaide Elec. has launched a new noise suppression tape, NRF-005T, using PULSHUT® (highly functional non-woven fabric) developed by Asahi Kasei Corporation.
PULSHUT® is a revolutionary noise suppression material that does not use any magnetic materials, and suppresses electromagnetic noise and radiation noise generated by AV equipment and cables, enabling reproduction of sound closer to the original sound. Oyaide Electric has commercialized the MWA Series of sendust alloy-based electromagnetic wave absorbers, which have been very well received as long-selling products.
In order to meet the needs of today's high-frequency noise-sensitive market, we have started to develop a new noise suppression material, NRF-005T, with the aim of achieving even higher performance.
Our focus is on avoiding "no fish in fresh water". This is because audio accessories that claim to absorb noise can filter out the nuances and realism that should be present in music and video without careful design, and can cause them to lose their vitality. NRF-005T solves the dilemma between noise reduction and original sound fidelity, providing a ground- breaking and innovative product for all audiophiles.
Conventional noise suppression materials have the property that the amount of noise suppression can be controlled by adjusting the magnetic material and the amount of magnetic material used. They have high magnetic loss characteristics and achieve their noise-absorbing effect by converting electromagnetic noise into heat. On the other hand, the impedance in certain frequency bands increases, which also affects the original sound waveform.
This is similar to the properties of ferrite cores. This means that, as with EMC/EMI countermeasures, appropriate noise countermeasures were necessary for audio as well. PULSHUT® is a highly functional non-woven fabric with a special surface treatment that provides high noise suppression performance despite its non-magnetic nature. This characteristic makes it possible to suppress only the noise component while minimising the effect on the original sound waves.
Improves sound quality
· Greater separation of voices and instruments
· Tighter bass and more refined treble
· Darker background silence
Just cut a short length (one inch for most interconnects)
· Wrap it around your cable at one end
Most effective on
· Unscreened cables
· Tone arm tubes
· Most screened cables
· Not so effective on high end cables with several screens
