What is Sound? Have you ever wondered, what exactly is sound? At its core, sound is a vibration that travels through a medium, such as air, water, or solid materials, in the form of waves. These vibrations reach our ears, and our brain interprets them as the diverse sounds we hear daily. these are a few facts about sound: - Frequency: Determines the pitch—whether a sound is high or low. - Amplitude: Impacts the volume—how loud or soft a sound is. - Medium: Sound travels fastest in solids, slower in liquids, and slowest in air. At EchoDynamics, understanding sound isn't just science—it’s our mission. Whether it's designing spaces for optimal acoustics or minimizing noise pollution, we specialize in crafting solutions that balance the art and science of sound. #SoundScience #Acoustics #EchoDynamics #AcousticEngineering

Our #Acoustic Consultants hard at work testing the #reverberation time of a meeting room and open space. The video demonstrates a very simple way to get an indication of the change of room acoustics, by popping a balloon! When the balloon is popped, the sound spreads in all directions, reflecting off the walls, ceiling, floor, and other surfaces. The sound decreases in level until it is no longer audible due to those reflections being absorbed. The reverberation time (RT60) of the room is determined by measuring the time it takes for the sound to decrease by 60 dB, or in practical terms, for the sound to disappear. #Acoustics #Hewshott #ReverberationTime

🤔 It often happens that the people we talk to have no idea where they can apply sound insulation and acoustics. To save you surprises and lift the curtain a little more, we have extracted for you and the readers of The City Media Group, some of the many scenarios in which you need to consult with an acoustic engineer 🎶🏢 Are you one of those people? See the article in the comments! Don't forget to share it, if you've found this useful! 🤗🔊 #SoundInsulation #AcousticEngineering #HomeImprovement #BuildingDesign #Soundproofing #ArchitectureTips #Acoustics #Soundproofing

How do we regulate Reverberation time and sound absorption? 🤔 Reverberation time refers to the duration it takes for sound to decay in a given space after the sound source has stopped. It is a fairly important factor in determining the acoustic characteristics of a room or an enclosed area. Longer reverberation times result in a more “lively" and "full" evironment, while shorter times create a more “dead” or absorptive space. Understanding reverberation time has its place in designing for an optimal acoustic climate. 🙌 In order to regulate the reverberation time it involves the process of reducing the reflection of sound waves from surfaces. Materials with high Sound Absorption Coefficients are effective in minimizing the amount of sound energy reflected back into the room. 🔇 Absorptive materials, such as acoustic panels, foams, diffusers, or specialized fabric, are strategically placed to control excessive reverberation and enhance speech intelligibility, music clarity, and overall sound quality within a given space. 🤫 #Acoustics #BuildingAcoustics #Noise #NoiseControl #ReverberationTime #DecayTime #Engineering #SoundAbsorption #RoomAcoustics

Do you see the difference ? Of course you do, because a system has developed in our eye that helps to form an image of what we are looking at. And this visual system has its peak at 555nm. The ancient methodology of calculating the efficiency of a light source peaks at the same point. However, looking at the total energy emitted by the two light sources in the picture, we can see that a common LED gives us much less energy, even though it is described as an efficient light source. The fault lies in the methodology for calculating the efficiency of a light source, which focuses solely on the visual system. Therefore, light sources that largely emit energy outside the visual (photopic) area are "inefficient" according to this methodology. As a result, unhealthy common LED sources that focus only on our visual system are preferred over healthy light today. And this is only because, in the age of artificial intelligence, we are using ancient methods by which we judge the quality of light. Wake up ! Let us not invest money in unhealthy technologies. Let us not prefer products that are 'efficient' only because of imperfect methodologies. Humans don't need light just to see ! We need more to be healthy ! ..............................................................................................................................

There is nothing permanent except change, and this is true also for acoustic measurements! In the most recent JASA paper by me, Sebastian Schlecht and Vesa Välimäki, we are looking into how time variance - resulting from, for example, temperature changes and movements of the air - affects room impulse responses. We develop a model to predict the loss of coherence between two RIRs associated with time-variant environment and predict the loss of energy that occurs when measurements are averaged, which is a common practice used to enhance SNR. See the published paper here: https://lnkd.in/dHj6p_FS Try it out yourself: https://lnkd.in/dDk9MFWw
