achieving only minor alignment errors of a few millimetres at worst. The loudspeaker dust cap at the membrane centre was used as reference in the manual alignment.
The loudspeaker dust cap at the membrane centre was used as reference in the manual alignment. During data post-processing, a spatial offset correction was applied based on a statistical evaluation given in Section 3.3. The corrected positions apply to the acoustical centre of the loudspeaker ...
The floor plane is a large reflecting surface. It is left untreated, to be an acoustic mirror effectively doubling the height of the room. Ceiling treatment must be accordingly more severe to keep the vertical decay and diffusion rate up with that of the walls. Fig. 3 – QSF Vocal Booth ...
(Symbol Pro 130, Magnat, Pulheim, Germany; frequency range: 35–30,000 Hz; high-frequency tweeter disabled for single membrane emission) with the speaker placed directly on the soil (centre of the membrane 9.25 cm above the soil, ~5 cm above the leaf litter). The sound reproduction ...

To describe the hardware in more detail, the DAC module is used to convert the digital signal to the output of the analog acoustic signals and drive the speaker into vibrations of the membrane, which are transmitted through the medium of air. The key module is reserved to start or stop the...
An additional polyethylene glycol shielding layer on the mono-nucleic acid/lipid particles (mNALPs) surface results in an increased particle stability under biomimetic conditions and prevents unspecific interactions with the cell membrane. Here we will focus on a particular formulation protocol leading to...
In healthcare, microphones and accelerometers have been the most commonly em- ployed sensors for acquiring acoustic and vibration signals. Microphones are acoustic sensors operating in the human audio frequency range (20–20,000 Hz) that are conventionally made of a flexible membrane and a back-...
