Insul 10 har släppts

INSUL Version 10 har nu släppts.

Utvecklingsteamet har utvärderat beräkningsalgoritmerna i INSUL och uppdaterat en stor del av dessa. De nya beräkningsrutinerna har validerats och testats för att verifiera noggrannheten.

Nyheterna är bl a Quadrupelkonstruktioner för väggar och bjälklag med upp till tre kaviteter.  En helt ny vågbaserad beräkningsmodell har tagits fram för beräkning av fönster och glas som beräknar modala responsen för tvåglas, treglas och fyrglasrutor.

Andra nyheter i Insul Version 10 är:

  • Custom illustration views kan sparas och hämtas
  • Nya regeltyper
  • Vidareutvecklad beräkningsmodell för enkel-, dubbel- och trippelkonstruktioner.
  • Uppdaterad beräkningsmodell för stegljud för dubbel och trippelkonstruktioner.
  • Uppdaterad rain noise model för dubbelkonstruktioner
  • Uppdaterade beräkningsmodell för reglar som tar mer hänsyn till reglarnas egenskaper.
  • Vidareutvecklade materialegenskaper för betong, gipsskivor och glas.

Mer information om quadrupelmodeller och den nya vågbaserade beräkningsrutinen för glas kommer senare.  Här finns ett produktblad om Insul 10 så länge:   INSUL-Version 10.

Om du vill testa Insul 10 kan vi erbjuda en tidsbegränsad trial licens. Kontakta i så fall Vibraphon info@vibraphon.se.

Insul 10

Insul version 10 planeras släppas i november. Den 23 oktober höjs priset på Insul. Alla beställningar som görs innan 23 oktober får nuvarande pris. Observera att 6 mån fria uppdateringar gäller, dvs en fri uppdatering till Insul 10 ingår om beställning görs senast 22 oktober.

ENC 6.0

Den stora nyheten med version 6.0 är modul 9 som innehåller ett SEA-program (Statistisk Energi Analys). Med SEA kan man beräkna hur vibrationer och stomljud utbreder sig i strukturer. Det kan hantera 50 element och 50 kopplingar. Det finns 25 typer av element och 39 kopplingstyper.

Iris at Philharmonie de Paris

IRIS at the new Philharmonie de Paris

IRIS was recently used by the MDA team at the commissioning of the new Philharmonie de Paris. IRIS proved to be an invaluable tool, achieving a full set of detailed measurements under challenging circumstances and a tight time frame (50 separate source/receiver measurements in 5 hours).

”IRIS performed flawlessly throughout the commissioning and the 3D rays enabled investigation of things instantly on site that would never have been possible with traditional measurement systems. The design of the hall is groundbreaking and being able to walk away with a 3D representation of the sound field in each position will also be invaluable for more detailed analysis in the future ” – Chris Day – Project Director

More about the measurements in the Philharmonie de Paris  PARIS – IRIS

IRIS is a new measurement system that promises to provide a dramatic step forward in being able to understand the acoustics of rooms. The system comprises a tetrahedral microphone that can resolve the sound field into different directions, and software that can analyse the signals from the four microphones and present the information in simple yet elegant way that aids ones understanding of the behaviour of the sound field.

  • IRIS is an affordable software and hardware 3D impulse response measurement system
  • Interactive 3D rotation and zoom
  • 3D colour-coded representation of sound rays
  • Length indicates relative sound intensity level, angle is the ray direction, and colour represents time of arrival
  • Specific angle and level information for individual rays for detailed analysis
  • Traditional omnidirectional waveform views
  • Broadband and octave band filtered views
  • EDT, T20, T30, D50, C80, Ts in octave band according to ISO 3382-1:2009
  • LF
  • G coming soon

dBSea

NEW! dBSea – Prediction of underwater noise

Despite what most people think the sea below surface is not very quiet. A lot of the sound sources are natural and is part of the background noise in the sea. Examples of natural noise sources are rain, interaction between wind and waves and also vulcanic activity can cause noise on far distance.

Many forms of marine life depend on sound for their communication, navigation and development. Noise generated by man can obstruct these vital functions and biologists are concerned about both physiological disorders as disorders in animal behavior. Especially in marine mammals, many species have very sensitive hearing. Noise generated by man in underwater environments include noise from ship traffic, pile driving and seismic surveys with impulse sources. EU Marine Directive descriptor 11 dictate that noise in the seas must not harm marine life. dBSea is a tool to comply with this Directive.

dBSea is a software for prediction of underwater noise. It uses several different prediction models and the user have full control over which to use depending on current application. The 3D model is built by importing bathymetry data and placing noise sources in the environment. Each source can consist of equipment chosen from either the standard or user defined databases. Noise mitigation methods may also be included. The user has control over the seabed and water properties including speed of sound profile (how the speed of sound changes with water depth), temperature, saltinity and current.

Noise levels are calculated throughout the entire project area and displayed in 3D. To examine results in more detail, levels may be plotted in cross sections or a detailed spectrum may be extracted at any point in the 3D calculation area.
