The aim of SOUND control is to coordinate, stimulate and assist with the initiatives to explore and implement a widely adaptable output-based framework applicable to substantiate the confidence of freedom and cost-effectiveness in current surveillance, control or eradication programmes for non-regulated cattle diseases in the EU.
Standardizing output-based surveillance to control non-regulated diseases of cattle in the EU. Several countries have implemented programmes to control non-regulated cattle diseases in the EU, impairing the comparison of the confidence of freedom for cattle originating from different countries.
Ambient Sound control is an auto-limiter on the noise canceling chip, which could be appealing in very specific scenarios. The 1000xm3 has 12 different modes in which it auto selects based on the environment. At first, I thought this might be handy for when someone ignores the fact that I'm wearing headphones and talks to me on the street/store/etc.... but it is far too hyper-sensitive and changes too many times, interrupting music, and DISABLING NC in noisy environments. I've found that simply using the palm-mute feature to be far more effective and causes less disruption to my music.
I've finally switched my desktop over to XFCE to match my laptop and I'm having a great time customizing it and getting things to look and work the way I want. One of those things is getting my sounds set up but, alas, I can't find the appropriate control panel. Possibly Fedora didn't install it, so I'd appreciate it if somebody would tell me its name so that I can install it.
OSC can be understood as a more flexible alternative MIDI; OSC clears away many of the ideological and hardware constraints inherent to MIDI in favor of a open-ended, user-defined address-space model that provides arbitrary parametric control via standard networking hardware. The OSC Specification 1.0 was formalized and published in 2002. The 2009 Specification 1.1 update added support for new features and data types. Over the years OSC has been useful in a wide variety of domains beyond musical contexts. Its timing accuracy and flexibility make it a ready solution for any application that requires time-sensitive communication between software and/or hardware endpoints.
When the Adaptive Sound Control is set to On, the Headphones Connect app detects where you are and what you are doing and adjusts the setting of the Noise Canceling or Ambient Sound Control. The notification sound tells you when the Noise Canceling or Ambient Sound Control setting change. Note: To disable the notification sound, open the Sony Headphones Connect app and, in the Adaptive Sound Control screen, turn off Notification Tone When Switching.

125 TRI MAX provides incredible sound isolation protection while simultaneously protecting the tile or stone finish from any cracking by reducing the transmission of stresses in the substrate through to the tile or stone finish.
-- Update: After some testing out, I found _volume_widget, which has mouse controls (scroll mouse to control volume, and click to toggle mute). Following the tutorial works on my box.
Sound, as a key vector of information and energy, is ubiquitous in our everyday lives. Its importance goes way beyond our daily conversations, and impacts a broad range of applications from the conception of noise-free systems, isolated buildings, to high-quality audio systems, medical therapy, and imaging. Yet, due to the macroscopically large wavelength and the broad frequency range involved, controlling audible sound with structured materials remains to date a difficult challenge1,2,3. Fundamentally, any passive causal acoustic structure is constrained by sum rules that translate into unavoidable bounds between the device size (in units of the acoustic wavelength) and the bandwidth of operation4. At low audible frequencies, where the sonic wavelength can be several meters long, acoustic solutions, for example absorbing walls or diffusers, are inherently massive. Devices based on narrow-band resonances, such as locally-resonant metamaterials, can however still be relevant in this regime, at the drastic cost of sacrificing the bandwidth, leading to remarkable but band-limited possibilities for perfect absorption3,5,6,7,8,9, assymetric transmission10,11, or wave bending and focusing, among others.
This vexing bottleneck may be avoided by breaking passivity and using active control schemes12. Applied to subwavelength acoustic resonators, active approaches have led to solutions with increased reconfigurability and bandwidth13,14,15,16,17. Unfortunately, such advances have remained relatively limited by inherent energy and stability constraints related to the inertia of the transducers used to implement them. Even in active schemes, based for example on electrodynamic or piezoelectric transducers, the achievable bandwidth can not be extended at will. This fundamental limitation is related to the increasingly large amount of energy required to actuate resonators far from their resonance condition, which leads to unavoidable instabilities, ultimately restricting the bandwidth.
In this paper, we propose to leverage the inherently non-inertial dynamics of ultrathin layers of air plasma to construct fundamentally broadband active plasmacoustic layers that can manipulate sound over >2 decades, with systems of unprecedentedly small sizes, down to λ/1000. Our method can manipulate an acoustic field by directly steering fluid particles, without resorting to any non-fluidic interface, simply by leveraging the partial ionization of air, controlled by an electrical field. Our theory of plasmacoustic metalayers unlocks the possibility to use the associated acoustic monopolar and dipolar sources to control the plasmacoustic surface impedance. We experimentally demonstrate practical applications of the concept to extremely thin and broadband perfect sound absorbers and tunable mirrors, with bandwith/size ratios at least 3 orders of magnitude larger than the currently available solutions.
The principal idea behind the design of the plasmacoustic metalayer is the use of a controlled dynamic corona discharge. This air-ionization phenomenon is used, for example, in flow control18, and for sound generation19,20,21. The plasmacoustic metalayer considered in this work is schematically illustrated in Fig. 1. It consists of two metallic electrodes separated by an air gap. One electrode (emitter) is represented by a set of thin wires and the second (collector) by a coarse grid. With such design, when no voltage is applied between the electrodes, the structure is acoustically transparent in the audible range. If the system is terminated with a rigid enclosure, an incident sound wave reflects without loss in amplitude (Fig. 1a). A completely different behavior occurs when the unit cell is supplied with power. If a positive constant high voltage is applied to the emitter while the collector is grounded, the magnitude of the electrical field can locally become higher than the breakdown threshold in air, causing an ionization process in a thin region around the emitter wire (violet glow in Fig. 1b). The produced positive ions further drift from the emitter to the collector electrode. Since the energy gained in the electric field in the main volume between the electrodes is not high enough to cause further ionization, the ions interact with surrounding neutral air particles in elastic collisions. This mechanism generates a constant force F that pushes the air particles. In the ionization region, a significant amount of the supplied power transforms into heat H through inelastic processes. If the voltage difference across the electrodes varies around a constant value, the fluctuation of the force and heat release can lead to sound generation. The force F acts as a dipolar acoustic source, similar to what happens in membrane-based electroacoustic actuators, yet with very small inertia. This dipolar response is indicated by the blue waves propagating with opposite phases and directions in the drift region. The fluctuation of heat has a monopolar influence on the generated acoustic pressure (red waves propagating in phase towards the two opposite directions). Altogether, these monopolar and dipolar acoustic sources have been created without resorting to inertial elements, escaping the inherent drawbacks of resonators, while being able to interact with the sound field in a controlled manner over an arbitrarily small thickness.
