Brainwave Synchronization

Psychoacoustic Effect

Psychoacoustic is fusion of psychology and acoustics science. Then it means that psychoacoustic is science exploring affect of sound (acoustics signal) to human psychology.

Sound can gives impact to human psychology depend on perception of that human. Perception is something which is influenced by interpretation mechanism on human brain. This is very difficult to be calculated and analyzed. This perception depends on biologic condition of human brain and ear.

Acoustic signal will influence the human behavior controlled by brain. For example, someone hear music then immediately a mini bomb is being blasted in near of him but that people doesn’t give any response. This effect is called masking effect. This effect is overlapping process of one incident to other incident managed by brain. In this condition, human brain produce brain wave concentrating that people to their music heard.

Other than that, the main effect on psychoacoustics science is hear perception depending on wave frequency. That is the main of psychoacoustics effect because the human ear can differentiate sound frequency before send it to brain. In our daily life, for example, a police serine has high frequency sound. This frequency is selected in order to break the human concentration. In contrast, in the low frequency, human can easily concentrate with what they do.

Instead get the frequency from the outside, human brain also produces the wave in some frequency itself. This wave frequency is correlated with the activity doing by its human. This wave frequency is in range within 0 to 100 Hz which can be separated to some kind.

Brainwave Synchronization

As we know, human brain produces some wave at some time. Our brain consists of billion of neurons connected each others. The combination of those neurons produces electrical activity which can be detected using medical equipment such as EEG. That electrical activity can be called brain wave pattern.

The pattern of brain wave correlates with human activity in same time. For example, the human brain wave when people is sleeping and walking is different. This pattern is also influenced by the human sense condition.

In the brainwave synchronization phenomenon, the sound heard by human will be separated by Bassiliar Membrane depend on its frequency level. The frequency sent to brain is the centre frequency. Brain will give the response with produce the wave with same frequency level.

Electroencephalography is the method to explore neurophysiology of brain elctrical activity by put the elctrode in the head skin. The result of this method is called electroencephalogram (EEG). This result rpresents the brain wave.

Four kinds of brain wave producing human brain based on EEG result:

• Alfa: Frequency range within 8,5-12 Hz. Thos wave is produced when we are relax.


• Beta: Frequency is more than 12 Hz. This wave is produced when we are bussy. This wave correlates with the concentration.


• Delta: Frequency is up to 4 Hz. Produced when we are sleeping.


• Teta: Frequency range within 4,5-8 Hz. This wave is prodeced when the human in twilight state. This wave kind correlates with intuition and creativity.

( Four kinds of wave produced by our brain......)

 

 

 

The exploration of this phenomenon (psychoacoustics and brainwave synchronization) gives many advantages to human especially to make brain produce the kind of wave they want. For example, if we want to make our brain to concentrate, we just hear the sound with exact frequency in right and left ear which can stimulate our brain to produce the beta wave.

Moreover, I and my team also has proposed that concept implemented to class for improving the student concentration in learning process. This concept is presented in Scientific Paper Competition in Education category held in Sepuluh Nopember Institutes of Technology (ITS) Surabaya, Indonesia at 2007 titled Implementation of Psychoacoustics-Brainwave Synchronization Effect for Improving Student Concentration in Learning Process.

Siti : Sales ‘Baso’ at 7 years old

I never see this television program, “Orang Pinggiran”. This program is aired by Trans7 television channel. However, because of somehow I watched this program yesterday, 6 March 2012. I have touched by little girl profile in that show. I changed the channel into this program until this program end.

Siti, 7 years old little girl, sales ‘baso’ made her neighbor for helping her mother finance. She is fatherless so her mother has to work hard for their live. Her mother is just a worker in her neighbor farm. They can’t get much money from that work. Usually she works but unpaid by her neighbor.

Although they are very poor but they are very love each other. Siti is studying at elementary school. In the noon, she goes to her neighbor to take the ‘baso’ for sale. She got 1000 to 2000 rupiahs for her sale each day. After that, sometimes,  she goes to her other neighbor to ask for vegetables for free. She needs it for her and her mother eating. In other day, they usually eat rice and salt only (how sad…).

Picture below shows the Siti and her mother in the ‘Orang Pinggiran’ program.

If you want to see more clearly, visit the facebook wioth account ‘Orang Pinggiran’ or you can follow the ‘orpingTrans7’ in Twitter. There are many response from the people who watched that program especially in the ‘Siti:Bocah Penjual Bakso’ edition.

The address below is the address of her if you want to help her. This contact is gotten from program facebook admin.

I am very sad for her. Her work for helping her mother although she is very little is good sample for us. Many good things can be gotten from this story. I think we have to think deeper about this, Why it happens? Who is in responsibility about this condition? We have to ask to ourselves….

Invisible Lecturer in Qur’an Learning

Al Qur’an is the holy book for Muslim contained of guidance for best lifestyle either for real world or heaven life. Thus, all of the Muslims have to understand and do all of commands in Al Qur’an. Then, to understand the means of Qur’an verse, the Muslim have to capable read correctly. For Indonesian, it is not easy because Al Qur’an is written with Arabic letter. Moreover there are many rules which is needed to be considered clearly by reader. If the reader doesn’t recite Qur’an verse properly then the meaning of Qur’an word and sentence recited will not same with the original.

In our life the learning process of recite Quran is still use the conventional method. The student has to meet directly with the lecturer. This lecturer is needed to be the evaluator of Quran  verse recited by student.

All of those ways of Qur’an verse learning ways, the many modern people now doesn’t want do that because they like the short way especially for the busy peoples who their daily life is full for working.

Some of months ago I have presented my research  at international conference in Yogyakarta.  which solve that problem. Actually, my purpose conduct this research is to provide the other way for Quran recitation learning using the newest technology so all of the people either common or busy people can use it easily. The title of my paper is “Prototyping of Qur’anic Verse Recitation Learning Software using Speech Recognition Techniques Based on Cepstral Feature”

In that paper I proposed the prototype step of Qur’an learning software equiped with novel method for evaluation of recitation correctness. This system using statistical machine learning  and cepstral features as basis of speech recognition technology used. So when we learn Qur’an recitatsion using this software, we fell that we are teached by virtual lecturer who is invisible. Below is the screenshoot of my paper and slide presented in the conference.

        

( my paper screenshoot in introduction and analysis section....)

Now we are working to upgrade the system for improving the performance especially in recognition. Currently, we develop the speech enhancement for this application so the reliability of this system environment can be developed. Then, the improvement of recognition rate in tajwid law is researched by my colleagues for his master thesis.

This research is done for my contribution for our religion, Islam. In our (my team and other peoples who help this research) mind, if this application has big performance so it can be used by all of Muslim than we plan to distributed freely. Insya Allah.

Kicau Sang Nanar : 4 Purnama

Empat purnama telah mengangkangi waktu
Seolah telah merasa lelah ia menunggu
Satu langkah gagah seorang kesatria lumpuh
Untuk menggenggam bayangan dalam pikiran semu

Ingatkah engkau empat purnama lalu
Di saat engkau berselimut emas menyilaukan
Berhias arang menyerang melintang curam
Ku di sana menatap cahaya mata mu tanpa lelah
Meski ku harus menyimpang dari arah tetapan

Ingatkah engkau empat purnama lalu
Saat waktu kembali mencoba berspekulasi
Memberi kesempatan meski sungguh sesaat
Namun kulewatkan dan hilang dalam satu kejap

Dari sana hingga empat purnama kini
Bayangan mu selalui menghantui pikiran
Lembaran kembarmu selalu menyakitkan perasaan
Dan jauh semerbak mu selalu merusak angan

Bukan cantik mu yang kubayangkan
Bukan indahmu yang menarik hati
Bukan senyummu yang menjadi dambaan
Namun entah kenapa hati ini merasakan sesuatu
Meski empat purnama telah berlalu

Pernah ku mencoba mengirimkan merpati tengah laut
Namun kauhunus dengan pedang keapatisan mu, keangkuhanmu
Lalu ku coba kirim sang matahari untuk mengwasi mu
Namun ia tak mau menyimpang dari jalannya

Terlalu lelah ku untuk meneruskan perjuangan
Kelumpuhan ku sudah kulminasi
Mungkin sebentar lagi hati kan menjadi beku
Dan purnama ke empat ini yang menjadi saksi
Dari kisah seorang kesatria dalam perang asmara.


Cinta takkan pernah menemui titik awal dan akhir. Sejak kita dilahirkan, cinta sudah tumbuh dalm hati seorang manusia. Takkan lebih manusiawi kecuali seorang manusia jatuh cinta.

Love will not meet the ending and beginning point. Starting we were born, love had grew up in the human heart. There is not human if they dont feel falling love.

Can't Take Back My Words (2)

Bandung, 040312

I have loosed. In my three application to study abroad, I have failed. All of those are my application to go to Europe university. However, I can't say more words. This is my way created by my God. What I have to do is still make the application and believe to the God. I dont have to underestimate about my way especially to my Greatest.

Pray, Hard Work and Believe are the key to get what I want, that is my idealism. No word "Always Failed". In the end of fail is the success. There is no rope without end. There is no sadness without happiness. If I do with my full power and capability, I can do it, whatever!!!!

I cant take back my words, I cant take back my step,  I cant take back my everlasting dream. Thanks to God....
