ANC reduces the overall input signal even when it has necessary information such as conversation as well as noise. In other words, conventional ANC has the disadvantage of reducing the required sound. On the other hand, there are scenes where conversation is desired even in a noisy environment. However, since the entire input signal is reduced, it cannot be solved even by using conventional ANC. We propose speech separation ANC system which separate announce and noise then control only noise component by ANC. To separate noise from the input signal, we focus on the signal separation method of spectral subtraction method and harmonic extraction method. These methods are simple and require a small computational load but have the disadvantage of leaving an estimated noise component. We also propose two signal separation methods which remain less noise component. In this paper, we verify the effectiveness of the proposed signal separation method while comparing it with the conventional signal separation method. Furthermore, the sound attenuation performance of the proposed method is confirmed by a control experiment in an anechoic room..

In a conventional masking, a masking sound is used to cover contents of conversation. This masking sound which is generated from a loudspeaker allow a third party not to understand what is said, but there is a problem that the sound level is increased because of a masking sound. Against this problem, we proposed Low-noise sound masking method using active noise control (ANC). The approach of this method is to make spectrum of phonemes flat by control sound. It is difficult to recognize phonemes that are processed by this method because the major factor determining the phonemes in speech recognition is the relative relationship of the peaks of its spectrum. In this paper, the sound attenuation performance of the proposed method is validated by control experiments in an anechoic chamber. Moreover, a listening experiment is carried out to investigate the sound masking performance. The result show that comparing with the conventional sound masking method, the proposed method can achieve the sound masking effect with a smaller sound pressure level..

Instead, around-head-control is investigated in this paper. In this system, two error microphones are set near ears, and noise is reduced around evaluation points locally. This system requires fast adaptation speed of controller following movement of head, and a problem still remains that the control effect during movement becomes worse. Against this problem, we propose Modified Reference signal Method (MRM). This method improves adaptation speed during movement, by modification of filtering of input signal in Filtered-x. The secondary path model that controller requires is interpolated by the method Ohno et al. proposed. There is modeling error of secondary path caused by interpolation and measuring error of it, and this modeling error causes divergence of controller. In this paper, suppression method of divergence is also investigated. Suppression of divergence is executed by addition of penalty term to evaluation value, and it is equivalent to ridge regression mathematically. Proposed method requires a large number of matrix calculations, therefore reducing method of computational complexity according to acoustic characteristics is also investigated in this paper. The validity of the proposed method is shown by numerical simulation and experiment..

The FF-ANC system can only reduce the noise downstream of the reference sensor due to the causality requirement. Therefore, a coupled FF control structure is proposed to realize the reduction of two-way diffraction. This system applies a two-source loudspeaker array as the control source, and two microphones as the reference and error sensors. The directivity of the loudspeaker array is controlled to emit the control sound only into the corresponding control area. In comparison with the preceding active diffraction reducing systems, using a directivity controlled loudspeaker array can generate an absorptive acoustic boundary rather than a reflective boundary on the diffracting edge, which can isolate the acoustic environment without adding reverberation in a room. The effectiveness of the proposed system is verified by computer simulations..

This soundproof system reduces and masks the undesired sound simultaneously so that lower level of the masker is required to achieve the sound masking effect, comparing with the conventional sound masking systems. First, a real-time experiment to verify the noise attenuation performance of the proposed system for practical application has been conducted in a real office room. In the experiment, the influence of background noise on the system performance has also been investigated. The experiment results show that 3-8 dB active noise attenuation can be achieved behind the ANB in an office room. Moreover, in order to select an appropriate masker for the sound masking part of the system, several maskers have been compared and investigated by listening experiments. The results suggest that the stationary maskers are more suitable for the sound masking in offices by considering the sound masking performance and the annoyance of the maskers comprehensively..

The FB control is preferred for this small-typed ANB application because only error sensor is required for the FB control system so that a compact controller can be easily realized. In practice, however, the robust stability of the FB controller must be considered. Moreover, the waterbed effect of the FB control will cause noise enhancement at some frequencies out of the target band of control. In order to design a robust controller with limited noise enhancement in real-time control, a modified frequency domain block LMS (modified FDB-LMS, MFDB-LMS) algorithm, which has the reduced computation complexity and the same steady-state performance comparing with the conventional FDB-LMS algorithm, is proposed in this paper, firstly, owing to the easiness to verify the robust stability and the noise enhancement constraints in the frequency domain adaptive process. Then, an internal model control (IMC) typed FB-ANC system exploiting the MFDB-LMS algorithm, into which the constraints to guarantee the robust stability and limit the noise enhancement to within a given value has been integrated, is proposed and applied to the ANB. The effectiveness of the proposed FB-ANC system and the noise attenuation performance of the ANB using the proposed system have been validated by simulations..

This hybird ANB reduces the diffraction noise from top of the ANB and the noise propagated to the head position of the target person behind the ANB simultaneously to achieve higher noise attenuation. However, the waterbed effect of the feedback control part of the HB-ANC system will cause noise enhancement at some frequencies in the control area. In order to solve this problem, the HB-ANC system is improved by adding a filter to cancel the noise enhancement caused by the waterbed effect. Then, the noise attenuation performance of the hybrid ANB under four sound field configurations is evaluated by simulations. The sound field configurations are set up to investigate how the diffraction from side of the ANB and the reflection influence the performance of the ANB. An experiment in the anechoic chamber is also conducted. The results indicate that the low frequency noise attenuation can be obtained in a wide area behind the ANB, and at the head position of the person, the noise attenuation can be ensured within a wider frequency range, even for the sound fields where the uncontrolled diffraction from side and the reflection exist..

The proposed system is a combination of feedforward and feedback controller. The reference signal for the feedforward controller is generated in the feedback part, so the reference microphone is not necessary. The feedback controller is used for controlling the acoustic boundary to insulate the diffraction noise, and the feedforward controller is used for reducing the noise at the error microphone which is set to be near the ears of people. As a preliminary work, this paper validated the effectiveness of the proposed ANC system both by simulations and by an experiment. The result shows that the active noise insulation provided by feedback controller and the noise attenuation provided by feedforward controller accumulated in the control area, so that the proposed ANC system has better control performance than individual feedforward or feedback ANC system..

However, these methods do not take into account a sound attenuation from viscosity. In our study, we propose a concentrated mass model which consists of spring-mass-damper system to perform a two-dimensional acoustic analysis. The dampers of this model consider viscosity of air. In this paper, we derive mass, connecting springs, and connecting dampers. The characteristic of connecting spring is derived from the condition of adiabatic change of air, and the connecting damper is derived from the normal stress. To confirm the validity of the proposed model, the numerical results obtained by the concentrated mass model are compared with the theoretical value of a traveling wave, and with the theoretical value of the natural frequency. All numerical computational results agree very well with the theoretical values. Therefore, it is concluded that the proposed model is valid for the two-dimensional acoustic analysis..

Instead, around-head-control is investigated in this paper. By using around-head-control method, an object person can get the noise reduction effect without controlling in the whole space, because it makes around the head quiet locally. Therefore, to realize around-head-control, it is necessary for a controller to follow the head movement. However, there is a problem that the control effect under the movement is worse, and the recovery of control effect after movement is slow by conventional ANC. Against this problem, we propose the new method of improving the adaptation speed when an evaluation point moves. In the algorithm, the updating size appropriate to each coefficient of the adaptive filter is calculated by using a step size vector. The step size vector is calculated from the coefficient of adaptive filter before updating. The validity of the proposal method is shown by the numerical simulation and the experiment in an anechoic chamber..

Floor impact noise such as the sound of footsteps or falling object becomes a problem in an apartment house. Floor impact noise has a peak at the low-frequency range. Passive noise control is not effective against low-frequency noise. Therefore, the purpose of this paper is to control the impact noise using active noise control. Since each impact noise is generated in a short period, LMS algorithm is difficult to use because of its slow convergence characteristics. On the other hand, frequency domain adaptive algorithm is known for fast convergence characteristics. In this paper, the effectiveness of active noise control using frequency domain adaptive algorithm is confirmed through simulations and experiments..

The HB-ANC system reduces the noise diffracted from the top of the ANB and the noise propagated to the head position of the target person behind the ANB simultaneously to achieve higher noise attenuation. However, the waterbed effect of the feedback control part of the HB-ANC system will cause noise enhancement at some frequencies in the control area. In the paper, in order to solve this problem, a filter able to cancel the noise enhancement is integrated into the HB-ANC system. Then, the noise attenuation performance of the ANB under four sound field configurations is verified by simulations. The sound field configurations are set up to investigate how the diffraction from side of the ANB and the reflection influence the performance of the ANB. An experiment in the anechoic chamber is also conducted. The simulation and experiment results indicate that the low frequency noise can be reduced in a wide area behind the ANB, and at the head position of the person, the noise attenuation can be obtained within a wider frequency range, even for the sound fields where the diffraction from side and the reflection exist..

This ANB exploits a hybrid active noise control (ANC) system with sound masking techniques to reduce and mask the target sound simultaneously, so less masker power is needed to achieve the same masking performance with the conventional sound masking techniques. In the previous work, the effectiveness of the ANB has been verified by computer simulations and by experiments in an anechoic chamber. In this paper, an experiment is conducted to verify the noise attenuation performance of the ANB in the sound field of a real office room. The influence of background noise on the noise attenuation performance of the ANB is also investigated in the experiment. Moreover, in order to select an appropriate masker for the sound masking part of the control system, several types of maskers are compared and investigated by listening experiments in this paper..
