摘要： The artificial reverberation generator employs a unidimensional wave guide (1) achieved by means of digital circuits, comprising at least two line sections of different lengths. Each section is comprised of two parallel delay digital arrangements, one for each propagation direction (2, 3), and between two adjacent sections there is arranged at least one three access adaptor used in the digital filtering art. Two out of the three accesses of the adaptor are each connected to one of the two adjacent terminations of said two line sections, whereas the depending access of a three access adaptor is connected to a selective absorber made by using the digital technique. With the digital realisation of a unidimensional wave guide provided with reflection points and absorbers, it is possible to obtain a diffuse reverberation and with a programmable frequential response of the reverberation time of a signal without having to support a reduction of the signal-to-rate ratio by limit cycles.

摘要： In these head-phones, which are provided with an orthodynamically actuated membrane, the airtight closing of the connecting space of the ear-phone is not effected and the connection to the ear is achieved by means of a pad made of cross-linked foam (1) which limits, at least laterally, the connecting space, the accoustic friction resistance of which being, when it is applied against the user's ear (2) or head, approximately of the same magnitude as the transformed characteristic impedance of air, so that the membrane (3) may work essentially with a slow-down due to friction and that a critical damping of the membrane's resonance (70-300 Hz), which is within the range of the low frequencies, may be achieved.

摘要： PURPOSE: To make the oscillator compact and to easily set and adjust it to oscillation conditions even in a wide frequency range by composing a feedback coupling four-terminal circuit of a spiral waveguide resonator in a two- or three-circuit section. CONSTITUTION: A frequency determination pf of the oscillator comprises the spiral waveguide resonator 4 in the two- or three-circuit section, and this resonator 4 sets and adjusts phase conditions needed for a desired operating frequency in a feedback path. Through this kind of oscillation generation, the vibrating function of the oscillator is automatically guaranteed in a frequency range of approximately 300 to 1,000MHz in practical use. Further, the size of the waveguide resonator 4 is so small that only a necessary space is practically needed. Consequently, the oscillator can easily be adjusted to its oscillation conditions in a wide frequency range and the oscillator can be made compact by a easy means.

摘要： PURPOSE: To obtain a microphone capable of obtaining direction and distance effects by applying a position corresponding to the position of human head to the aperture of a pinna, allowing the microphone to act as a directional microphone in a low frequency range up to about 1500Hz and utilizing the microphone for the spectral analysis of an external ear transmission function in a higher frequency range. CONSTITUTION: Imitation pinnas 1, 2 are respectively arranged in individual casings 13, 14, which can be rotated and revoluted. Unidirectional microphones 15, 16 are engaged with the insides of the pinnas 1, 2 so as to be inclined from the axes of the pinnas 1, 2 or so as to incline sound entering apertures and the positions of the pinnas 1, 2 correspond to the positions of ears on a human head.
