Acoustic Methods

Acoustic Methods – Acoustic Hailing Devices

Acoustic hailing devices (AHDs) direct sound signals
up to 150 dB in a beam which can be heard over 3,000 meters away.
Predator
bird cries and other noises disturbing to birds are transmitted.These
are powerful bird control solutions, and because of this power, they require
professional training for use. HyperSpike® systems from TONI come in a
number of specifications and configurations to meet different bird
control situations.

Important features of HyperSpike®
system
s

  • HyperSpike® is a flat
    phase-coherent acoustic pressure device. The top-of-the-line model can
    direct sounds (predator
    cries, disturbing noises, distress calls of various species) over 3,000
    m, and achieve acoustic pressure levels of 163 dB with a
    beam angle of +/- 5°
  • These systems carry a very low risk of habituation.
  • The system is set after the operations area is
    analyzed.
  • HyperSpike® AHDs are only allowed to be used by
    professional operators; a special user’s training course must
    be carried out before operations.
  • HyperSpike® systems are suitable
    for heavy populations.
  • Models are available in a variety of configurations for stationary, vehicle-mounted, or handheld use.
  • Each
    system comes equipped with standard accessories including MP3 player,
    microphone, and audio optimization software. Several models can be
    outfitted with additional accessories.

 

 

Advantages Disadvantages
  • Protects large areas
  • Low habituation
  • Automatic use with bird radar possible
  • Particularly effective when combined with LDU
  • Because the high acoustic pressure poses a risk to human hearing, manufacturer’s training is required
  • Relatively high price
