Pseudo-Active Noise Control for Small Caliber Rifles

  

  • Interlog’s MANCA technology provides active noise control both in the line of fire and downrange:
  • IAC to reduce overall amplitude up to 40 dBA in magnitude over a wide frequency band
  • AJS to edit acoustic signature of projectile flight (frequency and amplitude) in the downrange regime according to prescribed specifications, such as low-tune (200 – 600 Hz), mid-tune ( 600 -1000 Hz), and high-tune (1000 – 1500 Hz).

Meta-Material Liner for Hypersonic Vehicles

  

A new concept of Interlog’s meta-material liner enables a low-frequency, high-temperature, broadband (more than two octaves) reduction without increasing the liner depth and weight.
