Linear Simulation (LSIM)

Features and Benefits

  • Linear signal modeling from digital input to acoustical output
  • Lumped network parameters for passive components
  • Automatic equalization (DSP)
  • Small signal performance for any audio input (music, test signal)
  • Efficiency and voltage sensitivity versus frequency and broadband signals
  • Acoustical parameters from geometrical input

The LSIM Linear Simulation describes an active loudspeaker or headphone driver by using a linear lumped parameter model. The main components are equalizer, amplifier, transducer and enclosure. Using any selected input- spectrum (e.g. music), meaningful statistical single values (e.g. mean efficiency) and various state spectra (e.g. SPL) are calculated. This is a useful base for defining transducer and amplifier requirements and providing significant information about the audio performance. Various transfer functions reveal the relation-ship between digital, electrical, mechanical and acoustical signals.

The LSIM features an easy-to-use simulation software with lumped or geometrical input parameters for initial (small signal) design, which is the basis for the large signal simulation in other Klippel software modules (SIM Simulation, SIM AUR Auralization).
