Product/Service Info
Sound Design for Industry give your AUTOMOTIVE Engine sound design Active sound generation Mechanical sound refinement Sound for driving simulators products a new LEA is the premier software solution for sound design, sound analysis, sound quality and sound synthesis, and it is able to link sound to driving simulators, flight simulators and virtual reality platforms. LEA paves the way to target sound definition, brand sound creation, subjective and objective testing, component separation, troubleshooting and sound dataset preparation. Sound refinement for locks, seats, windows, air conditioning and windshield wipers AUDIO & TELECOM Telephones Audio systems Loudspeakers Speech intelligibility CONSUMER & LUXURY GOODS Home appliances: washing machines, refrigerators and vacuum cleaners DIY and garden tools Watches, alarm clocks, lighters, packaging For consumers, the sound of a product triggers a sensorial and emotional response, which has a direct impact on their buying decisions. A product’s sound provides information about the quality of the materials used and its craftsmanship. This is a selling point for your product and it is crucial to be able to control its impact. Sound level is just one parameter for maximizing sound comfort. Measuring and controlling it is a step further. It is more effective to refine a sound rather than simply trying to reduce it. 2 sound dimension Better sound, better life! Sound is everywhere, bringing us information and emotion, alerting us to potential threats and giving us the feeling of quality and comfort. GENESIS’s mission is to help companies to give their products a better sound. To provide a better customer experience, a distinctive sound signature, or for reducing the annoyance of air, rail or road transportation systems, sound matters for various reasons. Rather than simply reducing the noise level, it is more effective to investigate the components of the sound and analyze precisely the influence each component has on human perception. AEROSPACE Engine noise Cabin noise Fly-over noise Sound rendering in the cockpit RAILWAYS Passenger audio comfort Pass-by noise Train driver cabin noise INDUSTRIAL Diesel engines, turbo machines, wind turbines, pumps, electric motors and other applications: noise control, noise reduction, fault diagnosis Quality control, end of line tests, objective metrics for the pass/fail test DEFENSE Quietness evaluation Noise source identification Genesis contributes to a better world Through collaborating on projects aimed at reducing transportation noise and developing energy efficient technologies, Genesis demonstrates its commitment to a cleaner environment and quieter communities. Sound for sonar operator training simulator Sound for flying, driving and mission simulators Sound database 3 Target sound design Sound design LEA in ACTION Troubleshooting Annoyance assessment Psychoacoustic research Separation of sound sources 3D Sound playback SOUND SOURCE SEPARATION Acoustic analysis Order analysis Car electric starter The acoustic signal from a car’s electric starter allows for an in-depth analysis of the engine starting sequence. With just a few clicks, LEA separates the components of the sound, plays them and extracts the harmonics. The rotating speed profile is also extracted, and the behavior of the freewheel can be analyzed. “ I use LEA to analyze transient electric starter signals, which are short and random. I also use the tool do signal post processing, quantification of acoustic signals, vibration, voltage, temperature, etc.. I also do sound quality work... In fact, I use LEA for 90% of my work. The same tasks that used to take me half an hour using two or three programs now takes me only two minutes to do with LEA.” NVH Manager, Automotive supplier PSYCHOACOUSTICS LEA is able to calculate crucial metrics concerning noise perception inside and out of an aircraft. For example, to analyze the comfort level inside the cabin of a helicopter, LEA calculates standard indicators like Loudness (Zwicker - ISO532B), Sharpness, Roughness, Fluctuation strength and others. LEA offers the possibility to calculate a user-defined Comfort Index, based on Zwicker or polynomial form, to obtain an overall measurement of the comfort inside the cabin using only a single indicator. Additional indexes are provided for evaluating intelligibility and calculating the EPNL (required for aircraft and helicopter certification). “We use LEA everyday, mainly for target sound design, psychoacoustic indicator calculations, timefrequency sculptures and playback. We record the signals and sculpt the sounds in the time-frequency diagram, which then allows us to modify certain signal components. Then we analyze the results using psychoacoustic indicators and listening tests. LEA also allows us to create new signals to share with the decision makers to validate comfort modifications. In addition, GENESIS has equipped our studio with a playback system that perfectly reproduces the 3D Sound environment inside the cabin.” Cabin noise design Acoustics Engineer, Internal Noise Dept, Helicopter manufacturer 4 www.genesis-acoustics.com Engine Sound Design Sound quality expertise Signal denoising Jury testing SOUND DESIGN Audio dataset preparation for driving and flight simulators There are many applications for transient and impulsive sounds. Beyond the classic car door slam, LEA can also be used to analyze and improve the sound of locks, windshield wipers, switches and alarms. Sensorial marketing and expectations of quality make it also important to control the sound of watches, pen caps, lighters, packaging and chocolate bars (to name a few). Golf club Golf enthusiasts look for the perfect touch, the perfect sound. After using LEA to analyze the sound of their golf club, a famous golf club manufacturer was able to identify what sound was produced and how to control the various parameters. “With LEA we can define precisely our target sound and then ‘sculpt’ it. It is the secret our engineers use to modify the product accordingly.” Now, the greater sound precision of their clubs is widely appreciated by their customers. Sound Designer, Consulting Company ENGINE SOUND SYNTHESIS LEA provides an intermediary between sound synthesis, simulators and virtual reality platforms. With GeneCARS, the sound prepared with LEA can be tested in a Desktop Sound Simulator with a steering wheel, gears, a brake and a throttle. This sound can be loaded into a Driving Simulator with 3D sound capability for high-quality sound rendering. With GeneBOX, the target sound designed with LEA can be tested on the road in a vehicle. The driving parameters are acquired from the CAN bus and the sound is delivered through the audio system or headphones. Engine target sound determination “With LEA, creating time-frequency sculptures allows us to produce accurate sound databases without defects so much simpler and faster, and avoids re-recordings that are costly in both time and money. In addition, LEA brings us knowledge and practices that allow us to be more fluid in the way we work with sounds. We can highlight the characteristics of a sound and communicate by creating ‘sound cartoons’ for our customers, or internally, to talk to engineers who will work on the development of the object, making the link between the perception of sound and its time and/or frequency representation.” Team manager, Sound Perception and Sound Quality Dept, Car manufacturer 5 www.genesis-acoustics.com Unique architecture for performance and flexibility LEA can be adapted to fit your needs and applications. The standard package offers features for sound design and sound analysis. A series of optional modules provide access to dedicated functions, including order analysis, psychoacoustics, sound synthesis, 3D sound and sound simulation. LEA offers a set of exceptional features in a straightforward format that allows you to zero in on your critical tasks. While capable of performing advanced analytics and processes, LEA’s intuitive interface is easy to use and does not require a background in signal processing. LEA’s Time-frequency diagram is manipulated through the use of graphic Autosize FFT, Autoscale, zoom and slice display tools. The Magic Wand tool is a unique and efficient way to visually select a sound component. Other easy-to-use selection tools, like the line, rectangle, and freehand options, allow you to extract or modify any area in the time-frequency diagram. Any extracted component can be listened to, amplified, attenuated, combined with others and saved. The harmonic detector easily extracts the fundamental and any number of harmonics. It is also used to extract the RPM signal from a simple microphone signal, for order analysis or engine sound refinement. Sync Playback makes it easy to compare the original sound to the modified sound and instantaneously switch between the two during playback.
