    Abstract: Physical or perceived spatial signal/masker separation unmasks speech more when maskers are informational than when energetic. However, it is unclear how beneficial the separations are to cochlear-implant listeners, because signal transductions applied in cochlear implant degrade signals spectrally, and spectrally degraded speech is more vulnerable to maskers. Here, spectrums of both target speech (nonsense sentence) and masker (steady speech-spectrum noise, speech modulated speech C-spectrum noise, or speech) were filtered into 15 frequency bands. For both target and masking speech, the center-frequency pure tone of each band was modulated by the extracted envelope from the band. The target speech was composed by the sum of the 8 odd-band tones, and the masker was either same-band (with the 8 odd-band tones) or different-band (with the 7 even-band tones). The results show that physical but not perceived spatial separation unmasked target speech in naive normal-hearing listeners. However, following pre-presentations of both degraded and normal correspondent speech to listeners for a period of time or the introduction of phase information into modulated tones, perceived spatial separation reduced the influence of different-band speech masking but not that of same-band speech masking. These results are useful for improving cochlear-implant programs at both behavioral and technical levels.

    Abstract: Detecting acoustic signals in the ocean is crucial for port and coastal security, but existing methods often require informative priors. This paper introduces a new approach that transforms acoustic signal detection into network characterization using a MCN construction method. The method constructs a network representation of the acoustic signal by measuring pairwise correlations at different time scales. It proposes a network spectrum distance method that combines information geometry and graph signal processing theory to characterize these complex networks. By comparing the spectra of two networks, the method quantifies their similarity or dissimilarity, enabling comparisons of multi-scale correlation networks constructed from different time series data and tracking changes in nonlinear dynamics over time. The effectiveness of these methods is substantiated through comprehensive simulations and real-world data collected from the South China Sea. The results illustrate that the proposed approach attains a significant detection probability of over 90% when the signal-to-noise ratio exceeds −18 dB, whereas existing methods require a signal-to-noise ratio of at least −15 dB to achieve a comparable detection probability. This innovative approach holds promising applications in bolstering port security, facilitating coastal operations, and optimizing offshore activities by enabling more efficient detection of weak acoustic signals.

    Abstract: The goal of this study was to investigate the informational masking (IM) of Mandarin six-talker babble on Mandarin vowel and tone perception for native Chinese and Korean speakers with high and medium Mandarin proficiency. Mandarin Chinese speech sounds (vowel plus tone) were presented in quiet and two noises: six-talker babble and babble-modulated noise, which was spectrally and temporally matched with babble. The IM was computed as the difference in the identification scores between the two types of noises. Overall, all the four factors (listener group, noise type, vowel-plus-tone category, and SNR) significantly affected participants’ identification of Mandarin stimuli. Particularly, in both quiet and noisy conditions, Chinese listeners had comparable performance with Korean listeners with high Mandarin proficiency, while Chinese listeners significantly outperformed Korean listeners with medium Mandarin proficiency. However, no significant difference was found in IM among the listener groups. In conclusion, at the syllabic level, highly-proficient Korean listeners had native-like performance of Mandarin vowel and tone identification in quiet and noise, whereas Korean listeners with medium proficiency had greater difficulty, specifically in noise, likely due to their lower capacity to process phonemic and tonal information, rather than the IM of babble.

    Abstract: The impulse responses and other acoustical parameters of Huangpu Teenager Palace in Guangzhou were measured. Meanwhile, the acoustical simulation and auralization based on software ODEON were also made. The comparison between the parameters based on computer simulation and measuring is given. This case study shows that auralization technique based on computer simulation can be used for predicting the acoustical quality of a hall at its design stage.
