The binaural auditory steering strategy for hearing AIDS focuses to achieve a better hearing experience in terms of both "better ear" listening and situational awareness. We have taken into account the binaural auditory spatial processing strategy to optimize the acoustic beamforming filters. We investigate in this paper how human beings achieve better listening with cupped ears based on the head-related transfer function (HRTF) of the subjects with both open ears and cupped ears. We define the metrics better ear index and situational awareness index. We show that cupped ears can significantly improve the better ear index, and the open ears has better situational awareness. We can automatically choose one hearing aid with directivity similar to a cupped ear and another hearing aid similar to an open ear to achieve both better intelligibility and situational awareness in certain acoustic environments.

This article describes the perspectives of hearing device manufacturers regarding the exciting developments that the Internet makes possible. Specifically, it proposes to join forces toward interoperability and standardization of Internet and audiology.A summary of why such a collaborative effort is required is provided from historical and scientific perspectives. A roadmap toward interoperability and standardization is proposed.Information and communication technologies improve the flow of health care data and pave the way to better health care. However, hearing-related products, features, and services are notoriously heterogeneous and incompatible with other health care systems (no interoperability). Standardization is the process of developing and implementing technical standards (e.g., Noah hearing database). All parties involved in interoperability and standardization realize mutual gains by making mutually consistent decisions. De jure (officially endorsed) standards can be developed in collaboration with large national health care systems as well as spokespeople for hearing care professionals and hearing device users. The roadmap covers mutual collaboration; data privacy, security, and ownership; compliance with current regulations; scalability and modularity; and the scope of interoperability and standards.We propose to join forces to pave the way to the interoperable Internet and audiology products, features, and services that the world needs.

IEEE Transactions on Antennas and Propagation | Year: 2016

A novel concept for an electrically small on-body antenna targeted for 2.4 GHz ISM band custom in-The-ear (ITE) hearing instrument (HI) applications is introduced. The antenna is based upon a cavity-backed design in order to take advantage of the maximum volume available ITE while providing isolation from the user's body, and it occupies only 40% of the volume of the sphere with radius a = 12mm. The antenna is implemented on a realistic three-dimensional (3-D)-printed lossy substrate and exhibits high efficiency of 70% and 22%, and a 6-dB impedance bandwidth of 108 and 149 MHz, when the antenna is measured in free space (FS) and ITE, respectively. A measurement campaign conducted in FS and on a specific anthropomorphic mannequin (SAM) head with ears shows that the radiation pattern is optimal for HI applications. Furthermore, the antenna is primarily polarized normal to the surface of the head to ensure the best on-body path gain (PG). This is substantiated by the study of the ear-to-ear (E2E) PG, which is measured and compared to analytic and numerical results. © 2016 IEEE.

Sounds are said to be externalized when we hear them originate from outside the head. This paper investigates if visual stimuli alone can inuence the perceived externalization. An externalization test is performed on six normal hearing test subjects in three different environments where the visual stimuli is varied and the sound stimuli held constant using headphone based virtual sound. The virtual sound stimuli are based on the test subjects' own Head-Related-Transfer-Functions (HRTFs). Significant differences (p < 0:001) are observed on the externalization performance when the visual impressions of the test rooms is varied. It is concluded that auditory externalization not only rely on the acoustic stimuli but also on visual impression of the room in which the sound source is located in.

Spectral Doppler ultrasound imaging typically consists of a spectrogram, showing the velocity distribution of the blood, and a brightness (B-) mode image allowing the operator to navigate. It is desirable to have both high spectral and velocity resolution, so that details in the blood flow can be traced, as well as a high B-mode frame rate to allow for tracking of movements and to adjust the position of the transducer. The blood flow signal is often sampled 1) using alternating transmissions for blood flow estimation and for B-mode imaging, or, 2) by acquiring a full Doppler spectrum and then parts of the B-mode image. The former has the disadvantage that it halves the sampling rate, making it likely that aliasing will occur when imaging fast moving blood or deeply positioned vessels; the latter that gaps appears in the spectrogram, and that if the frame rate of the B-mode images is slow, it will be difficult to track movements. Adaptive methods have been implemented to circumvent such problems, but even so, to get an acceptable frame rate of the B-mode images, the number of transmissions for Doppler estimation will be limited, restricting the spectral resolution. Alternatively, one may use an irregularly spaced emission pattern, but existing work on the topic is limited and generally suffers from poor resolution and spurious velocity components resulting from the irregular sampling pattern. In this paper, we examine the BIAA algorithm, showing that this approach allows for an accurate velocity estimate even from irregularly sampled measurements. Using an irregular emission pattern, with half the emissions used to form the B-mode image, the remaining emissions are found to yield accurate velocity estimates without reducing the maximally measurable velocity and without the spurious velocity components. Moreover, we show that the approach will allow for the same maximal velocity without aliasing as if all emissions would have been used for the velocity estimation. © 2012 IEEE.

Spectrograms in medical ultrasound are usually estimated with Welch's method (WM). WM is dependent on an observation window (OW) of up to 256 emissions per estimate to achieve sufficient spectral resolution and contrast. Two adaptive filterbank methods have been suggested to reduce the OW: Blood spectral Power Capon (BPC) and the Blood Amplitude and Phase EStimation method (BAPES). Ten volunteers were scanned over the carotid artery. From each data set, 28 spectrograms were produced by combining four approaches (WM with a Hanning window (W.HAN), WM with a boxcar window (W.BOX), BPC and BAPES) and seven OWs (128, 64, 32, 16, 8, 4, 2). The full-width-at-half-maximum (FWHM) and the ratio between main and side-lobe levels were calculated at end-diastole for each spectrogram. Furthermore, all 280 spectrograms were randomized and presented to nine radiologists for visual evaluation: useful/not useful. BAPES and BPC compared to WM had better resolution (lower FWHM) for all OW < 128 while only BAPES compared to WM had improved contrast (higher ratio). According to the scores given by the radiologists, BAPES, BPC and W.HAN performed equally well (p > 0.05) at OW 128 and 64, while W.BOX scored less (p < 0.05). At OW 32, BAPES and BPC performed better than WM (p < 0.0001) and BAPES was significantly superior to BPC at OW 16 (p = 0.0002) and 8 (p < 0.0001). BPC at OW 32 performed as well as BPC at OW 128 (p = 0.29) and BAPES at OW 16 as BAPES at OW 128 (p = 0.55). WM at OW 16 and 8 failed as all four methods at OW 4 and 2. The intra-observer variability tested for three radiologist showed on average good agreement (90%, κ = 0.79) and inter-observer variability showed moderate agreement (78%, κ = 0.56). The results indicated that BPC and BAPES had better resolution and BAPES better contrast than WM, and that OW can be reduced to 32 using BPC and 16 using BAPES without reducing the usefulness of the spectrogram. This could potentially increase the temporal resolution of the spectrogram or the frame-rate of the interleaved B-mode images. © 2009 Elsevier B.V. All rights reserved.

Dynamic-range compression (DRC) is used in the music industry to maximize loudness. The amount of compression applied to commercial recordings has increased over time due to a motivating perspective that louder music is always preferred. In contrast to this viewpoint, artists and consumers have argued that using large amounts of DRC negatively affects the quality of music. However, little research evidence has supported the claims of either position. The present study investigated how DRC affects the perceived loudness and sound quality of recorded music. Rock and classical music samples were peak-normalized and then processed using different amounts of DRC. Normal-hearing listeners rated the processed and unprocessed samples on overall loudness, dynamic range, pleasantness, and preference, using a scaled paired-comparison procedure in two conditions: un-equalized, in which the loudness of the music samples varied, and loudness-equalized, in which loudness differences were minimized. Results indicated that a small amount of compression was preferred in the un-equalized condition, but the highest levels of compression were generally detrimental to quality, whether loudness was equalized or varied. These findings are contrary to the louder is better mentality in the music industry and suggest that more conservative use of DRC may be preferred for commercial music. © 2012 Acoustical Society of America.
