Loudspeaker modeling program
A loudspeaker or speaker driver , or most frequently just speaker is an electroacoustic transducer , [1] that is, a device that converts an electrical audio signal into a corresponding sound. The speaker driver can be viewed as a linear motor attached to a diaphragm which couples that motor's movement to motion of air, that is, sound. An audio signal, typically from a microphone, recording, or radio broadcast, is amplified electronically to a power level capable of driving that motor in order to reproduce the sound corresponding to the original unamplified electronic signal. This is thus the opposite function to the microphone , and indeed the dynamic speaker driver, by far the most common type, is a linear motor in the same basic configuration as the dynamic microphone which uses such a motor in reverse, as a generator. The dynamic speaker was invented in by Edward W.

Updated rated load capacities of the Meyer Sound rigging assembly for different splay angle settings when using the Pullback Frame options provided are based on testing performed by an independent testing agency, and on 5 to 1 safety limit analysis to ultimate load performed by an independent structural engineering firm.
The ratings apply to the Meyer Sound rigging only. For more information, please contact Meyer Sound Technical Support. Rated load capacities of the Meyer Sound rigging assembly for different splay angle settings are based on testing performed by an independent testing agency, and on 5 to 1 safety limit analysis to ultimate load performed by an independent structural engineering firm. LYON-WXT has the same horizontal dispersion and acoustical properties as a standard LYON-W but has greater vertical dispersion, so fewer elements are needed to achieve wider vertical coverage in large, multi-level venues.
LYON-WXT is particularly effective when used for downfill at the bottom of extremely curved arrays, such as those used near or directly above the stage for in-the-round arena coverage. Enhancement and fixes to Flown Loudspeaker System.
A simple SPL number on a datasheet does not reflect the essential characteristic of highly linear systems: that they do not change their sound when the level is increased. With the ability to store and recall traces in MAPP XT, you can view combined systems with this new data, and verify that system designs have sufficient headroom. Gaussian Variability Enhancement Algorithm To give better simulations of real world measurements, a new algorithm has been added to MAPP XT that simulates the small natural variability in our loudspeakers.
Before this algorithm was added, all loudspeakers of the same model in MAPP used the same measured complex polar data set. This had the unintended effect of creating infinite nulls for example , which never happens in physical measurements. While Meyer Sound loudspeakers are extremely consistent, they are not perfectly identical. There is no possibility of the algorithm producing incorrect results, but since the algorithm is applied each time you predict, there will be slight differences between predictions.
Cardioid arrays are achieved by placing three units coplanar to each other in either a ground stacked or flown array with one unit facing the opposite direction. The output of the reversed loudspeaker cancels the output of the other loudspeakers that is normally present behind the units, while also increasing SPL directed forward. Once inserted into the sound field, they can remain a gradient subwoofer array object that automatically assigns the correct delay time for the second processor channel.
To override any of these automated settings, the object can be converted to a flown loudspeaker system. Auto-Splay is only available when a single flown loudspeaker system is selected along with a single Listener Plane.
A Listener Plane is a converted Architectural Visual Aid that represents an audience area facing the loudspeaker system. Listener Planes can be divided into one or more reference zones. Once the loudspeaker system is selected, along with the Listener Plane, choose Auto-Splay to estimate the optimum splay angles for the system.
When the single flown loudspeaker system is selected along with the Listener Plane, the Auto-Splay feature can be used to obtain array starting angles. The memory trace plots display in different colors along with the live trace in all available measurement modes.
The traces can be displayed or hidden on demand. User credentials can also be cleared from the settings menu. Using the Auto-Set Delay button inserts delay on the source signal so the relative time between the source signal and the measured signal is zero. They will be disabled for products i. If the configuration exceeds the mechanical load limits, a warning is displayed in the edit loudspeaker system properties: Rated load capacities of the Meyer Sound rigging assembly for different splay angle settings are based on testing performed by an independent testing agency, and on safety limit analysis performed by an independent structural engineering firm.

10 Best Free Speaker Design Software For Windows
SPEAK is a very old program, but one that is still quite useful. It is a free download, but it is unsupported. In today's demanding environment for loudspeaker designs, designing for a flat axial response is simply not enough. Speak is a high performance loudspeaker modeling package aimed at the knowledgeable designer of loudspeaker systems. Even though Speak is a highly sophisticated software application, its ease of use makes it a highly effective education tool for the more novice practitioner.

Rooms can be defined using a CAD module, absorption coefficients can be assigned to surfaces, and sound sources as well as listener positions can easily be added to the model. They assist designers in learning and growing by graphically displaying accurate predictions of real-world acoustics. These data can then be used to generate an exact simulation of reverberation times, speech intelligibility and other acoustical parameters even before the room itself is built. Worldwide, thousands of acousticians, consultants, specifying engineers, installation companies and other professionals rely on EASE for their everyday work by now. EASE has not only been setting the standard in simulation, it also was the starting point for a row of additional modules and other programs that, over the years, have greatly expanded the capabilities of EASE as well as the quality of acoustical simulation as a whole. Using the EASE modeling tools an acoustical model can be built quickly. Closed rooms can be modeled in addition to open spaces, such as arenas and stadiums.
EASE Focus 3 is a three-dimensional, acoustic simulation software for the configuration and modeling of line array systems and of adjustable loudspeakers, such as digitally steered columns. EASE Focus 3 is free for the end user. In EASE Focus 3, each line array or column loudspeaker is described by a so-called system definition which contains the mechanical, electronic and acoustic properties of the loudspeaker system.
The objective of this lab activity is to measure the impedance profile and the resonate frequency of a permanent magnet loudspeaker. The chief electrical characteristic of a dynamic loudspeaker is its electrical impedance as a function of frequency. It can be visualized by plotting it as a graph, called the impedance curve. The most common type of loudspeaker is an electro-mechanical transducer using a voice coil connected to a diaphragm or cone. The voice coil in moving coil loudspeakers is suspended in a magnetic field provided by a permanent magnet. As electric current flows through the voice coil, from an audio amplifier, the electro-magnetic field created by the current in the coil reacts against the permanent magnet's fixed field and moves the voice coil also the cone.

A basic predefined electroacoustic model is used to derive frequency response graphs, impedance plots and so on. Builders often purchase modelling software in an attempt to design and build cheaper, and hopefully better, loudspeaker systems in comparison to commercially-available units. Accurate loudspeaker simulation software are often very expensive, often the cost of such a package is greater than a commercially-available loudspeaker system.
