Patent number: 10841717Abstract: A noise generator and method are provided for generating a test signal for measuring the performance of a loudspeaker over an operating broad band of frequencies ranging from low to high frequencies. A broadband random noise source is provided for generating broadband noise over the operating broad band of frequencies of the loudspeaker, and an impulsive noise source is additionally provided for generating random impulses of noise. The broadband noise and the randomly generated noise impulses are equalized to produce a composite noise signal having a desired crest factor as a function of frequency.Type: GrantFiled: June 17, 2019Date of Patent: November 17, 2020Assignee: Meyer Sound Laboratories, IncorporatedInventors: John D.

Publication number: 20200071645Abstract: An apparatus for modifying a responsive liquid held in a barrel or other liquid container includes a transducer for producing vibration energy within the audio frequency range in response to an audio signal input and a coupler affixed to the transducer such that vibration energy produced in the transducer is transferred to the coupling device. The coupling device has a pusher end that extends beyond the front plane of the transducer and that contacts and pushes against the barrel wall when the apparatus is tied to the barrel wall. By determining the resonances of the liquid-filled barrel, audio input signals having sufficiently high levels at determined resonant frequencies can be chosen to achieve a maximum response in the liquid contained in the barrel. The apparatus is particularly suited for the sonic aging of whisky.Type: ApplicationFiled: November 8, 2019Publication date: March 5, 2020Inventors: John D. Meyer, Katrin M. Rawks, Jon Arneson, Paul Kohut, Roger Schwenke, Pei-Yuan Liu, Carlo Zuccatti

Patent number: 10375484Abstract: An improved open-ear hearing aid to compensate for hearing loss includes a microphone for picking up incident sound and converting it to an electrical audio signal. An ear insert positionable within a human ear canal is provided for producing an output sound amplified within one or more frequency bands in response to incident sound picked up by the microphone. The in-band gain of the amplified sound output of the ear insert's loudspeaker is dependent on the user's hearing loss characteristics and the sound pressure levels of the incident sound. The form of the ear insert allows transmission of incident sound directly to the eardrum, where it is summed at the eardrum with the amplified sound output from the ear insert. Sound output is maximum at low incident sound pressure levels and minimum when the incident sound exceeds a set cut-off level.Type: GrantFiled: September 11, 2015Date of Patent: August 6, 2019Assignee: Meyer Sound Laboratories, IncorporatedInventors: John D. Meyer, Toban A. Szuts

Patent number: 10299047Abstract: The hearing aid includes a signal processor having a level-dependent filter section and a level-independent filter section. The level-dependent filter section provides level-dependent gain wherein sound is attenuated or amplified depending on the level of the incoming sound. The level-independent filter section provides substantially constant gain wherein sound that passes through the filter section is not changed in level, and provides transparency in that it corrects for insertion loss caused by the earpiece of the hearing aid when worn by the user. The level dependent and level independent filter sections, when fitted to the user, greatly improve the user's perception of sound.Type: GrantFiled: August 31, 2017Date of Patent: May 21, 2019Assignee: Meyer Sound Laboratories, IncorporatedInventors: John D. Meyer, Toban A. Szuts

Publication number: 20190132676Abstract: A filter for correcting phase distortion produced at low frequencies in a loudspeaker system is created by inverting the phase response of the determined complex-valued frequency response of a loudspeaker system. The inverted phase response is obtained by taking the complex conjugate of the phase response. The impulse response for the inverted phase response is obtained by means of an inverse Fourier transform of the inverted phase response. The impulse response provides a linear phase FIR filter having a long filter length. The linear phase FIR filter is applied to the audio signal input to the loudspeaker system. Prior to inverting the phase response, the determined complex-valued frequency response of a loudspeaker system can be subjected to high frequency blanking and polynomial smoothing. Also, the linear phase FIR filter can be subjected to a window function prior to applying the filter to the audio signal.Type: ApplicationFiled: June 4, 2018Publication date: May 2, 2019Applicant: Meyer Sound Laboratories, IncorporatedInventors: Perrin Meyer, John D.
