A sound system in classroom application is a formal letter written by students to the Principal or the Headmaster of their school or college, requesting a sound system for their classrooms. In many schools and colleges of Bangladesh, especially in large classrooms and hall rooms, hundreds of students sit together for a single class. The teacher speaks from the front of the room, but the students sitting on the middle benches and the back benches cannot hear the lecture clearly. Their studies suffer, they miss important points, and they slowly lose interest in the lesson. A sound system with a microphone and speakers can solve this problem completely. It carries the teacher's voice to every corner of the room, so every student can listen, understand, and learn equally. Because this application is written on behalf of the whole class, it is one of the most common and important applications in the SSC and HSC English examinations. Learning it well will help you in the examination and in real school life.

What Is a Sound System in Classroom Application for School Students

A sound system in classroom application is a request letter in which students describe a real problem of their classroom and ask the school authority to solve it by installing a sound system. It is different from a personal application, such as an application for leave or a transfer certificate, because it is written on behalf of many students. The application is usually signed by the class captain or a representative student, and it mentions the class, the section, and the number of students who face the problem.

The problem is very common in Bangladesh. In many schools, the Bangla, English, and Mathematics classes of Class 9 and Class 10 are held in large rooms, and in colleges, the compulsory subjects are taught in big hall rooms with two hundred or three hundred students. When the room is large and the students are many, the teacher's natural voice cannot reach the back of the room. The students at the back cannot follow the lecture, they cannot take proper notes, and their examination results become poor. A sound system removes this problem at a small cost. The microphone makes the teacher's voice clear, the speakers spread it evenly, and every student hears the lesson in the same way.

Sound System in Classroom Application Format for Class 6, 7, 8, SSC, HSC

Every sound system in classroom application follows the same formal format. Learning this format once will help you write any kind of school application in the exam hall and in real life. The table below shows the parts of the format at a glance.

Sender's address: Write your own address at the top of the application. It usually contains the house or village name, the area, and the district. For example: 12, Green Road, Dhanmondi, Dhaka.

Date: Write the date just below your address. Always write the full date, for example, 27 October 2026.

Recipient: Write the name and designation of the person you are writing to. It can be The Principal or The Headmaster, followed by the name and address of the school. In most schools, an application for a sound system goes to the Principal or the Headmaster, because only the head of the institution can approve the purchase of equipment.

Subject: The subject line tells the reader the purpose of the letter in one line. A good subject for this application is: Application for providing a sound system in the classroom or Prayer for providing a sound system in the large classrooms.

Salutation: Begin with a respectful greeting such as Respected Sir or Respected Madam. If you do not know whether the recipient is a man or a woman, write Respected Sir/Madam.

Body: The body has three short paragraphs. The first paragraph introduces you and states the purpose of the letter. The second paragraph describes the problem: the classroom is large, the number of students is great, and the students at the back cannot hear the teacher. The third paragraph requests the sound system politely and explains how it will improve the studies of all the students.

Closing and signature: End with a polite closing such as Yours obediently. Then write your full name, class, section, and roll number. If you are writing on behalf of the class, add the words "On behalf of the students of Class 9" below your name.

Sound System in Classroom Application to the Principal for Large Classrooms

This is the most important sample in this post. It is a full and detailed application to the Principal, suitable for students of Class 8, Class 9, Class 10, SSC, and HSC. It describes the problem clearly, gives the number of students, and explains the benefit of a sound system. This is the model to learn by heart for the examination.

27 October 2026

The Principal,

Ideal High School, Dhaka

Subject: Application for providing a sound system in the large classrooms.

Respected Sir,

With due respect, I beg to state that I am a student of Class 9, Section A, of your school. On behalf of the students of our class, I am writing this application to draw your kind attention to a serious problem we are facing in our classroom.

Most of our classes are held in the large hall room of our school. More than two hundred students attend the Bangla, English, and Mathematics classes together. The room is so large that the students sitting on the middle benches and the back benches cannot hear the lectures of our teachers clearly. As a result, they cannot follow the lessons, they cannot take proper notes, and their studies are being greatly hampered. We have informed our class teachers about this problem many times, but the problem is yet to be solved.

We think that this problem can be easily solved if a sound system is provided in our large classrooms. A microphone and a few speakers will carry the teacher's voice to every corner of the room, and every student will be able to listen to the lectures clearly. It will improve our concentration, our notes, and our examination results.

I, therefore, pray and hope that you would be kind enough to take necessary steps for providing a sound system in the large classrooms of our school and oblige us thereby.

Yours obediently,

Rahim Uddin

Class 9, Section A, Roll No. 05

Application to the Headmaster for a Sound System in the Classroom

Notice how it mentions the hall room and the number of students, because these two facts make the problem clear and the request reasonable.

The Headmaster,

Sunrise High School, Chattogram

Subject: Prayer for providing a sound system in our classroom.

Respected Sir,

With due respect, I beg to state that we, the students of Class 8, Section B, of your school, are facing a great problem in our classroom. Our classes are held in the hall room, where more than one hundred and fifty students sit together.

The hall room is very large, and the teachers cannot make their voices reach the back benches. The students who sit at the back cannot listen to the lectures properly, so they miss many important points of the lessons. This is hampering our studies badly.

We, therefore, request you to kindly arrange a sound system for our classroom as early as possible. A sound system will help every student to hear the lectures clearly and to learn better.

I shall remain grateful to you for your kind consideration.

Yours obediently,

Tanvir Hasan

Class 8, Section B, Roll No. 12

So, I request you to kindly give us a sound system for our classroom. Then every student will be able to hear the lessons and learn well.

Yours obediently,

Useful Phrases and Sentence Patterns for Sound System Applications

Good applications are built from good sentences. Learn the following phrases and use them in your own application. They will make your writing sound polite, formal, and natural.

• Opening the application: "With due respect, I beg to state that I am a student of Class..."

• Writing on behalf of the class: "On behalf of the students of our class, I am writing this application to draw your kind attention to a serious problem."

• Describing the problem: "The students sitting on the middle benches and the back benches cannot hear the lectures of our teachers clearly."

• Mentioning the size of the room: "Our classes are held in the large hall room, where more than two hundred students attend together."

• Explaining the effect: "As a result, our studies are being greatly hampered, and we cannot take proper notes."

• Proposing the solution: "We think that this problem can be easily solved if a sound system is provided in our classrooms."

• Mentioning the benefit: "A sound system will carry the teacher's voice to every corner of the room and help every student to learn better."

• Closing politely: "I, therefore, pray and hope that you would be kind enough to take necessary steps and oblige us thereby."

A strong sentence pattern for the problem is: "The classroom is so large that the students at the back cannot hear the teacher clearly." Another useful pattern is: "Due to the large number of students, the teacher's voice does not reach the back benches." Keep the problem specific and the numbers real. A vague problem such as "we have a problem in class" is weak, while a clear problem such as "two hundred students sit in the hall room and the back benchers cannot hear the lecture" is easy to approve.

The table below gives the meanings of the difficult words used in this post. Learn them so that you can understand the application and use the words correctly in your own writing.

Class-Wise Guidance for Writing a Sound System in Classroom Application

For Class 6 and Class 7: Keep the application short, about 100 to 120 words. Use simple sentences and easy words. Mention that the classroom is large and the back benchers cannot hear the teacher. You can write the application by yourself or with the help of your class captain. Do not use difficult words you cannot spell correctly in the examination.

For Class 8 and Class 9: Write a medium-length application of about 130 to 160 words. Mention the hall room, the number of students, and the subjects that are held in the large room. Explain how the problem harms the studies of the students. You can address the application to the Headmaster or the Principal.

For Class 10, SSC, and HSC: Write a full and polished application of about 150 to 200 words. Use formal vocabulary such as "draw your kind attention", "our studies are being greatly hampered", and "take necessary steps".

In the examination, the examiner gives marks for the correct format, a clear description of the problem, the polite tone, and correct grammar.

For all classes, remember that this application is a group request, not a personal request. Write "we" more than "I", because you are speaking for the whole class. Always mention the number of students and the size of the room, because these facts prove that the problem is real. And always check the spelling of "Principal" and "Headmaster" before you submit the application.

Common Mistakes in a Sound System in Classroom Application

Students lose marks and sometimes lose approval because of a few common mistakes. Avoid them in your application.

• Writing it as a personal request: This application is for the whole class, not for one student. Write "we, the students of Class 9" and "on behalf of the students", not only "I want a sound system."

• Forgetting to mention the number of students: The number of students is the main proof of the problem. Always write how many students sit in the room.

• Writing a vague problem: "We have a problem in our classroom" tells the reader nothing. Write the real problem: "The back benchers cannot hear the teacher's lectures."

• Missing the subject line: The subject tells the reader the purpose of the letter in one line. Never skip it.

• Wrong spelling of Principal: Many students write "Principle" instead of "Principal". The head of a school or college is always "Principal".

• Informal language: Do not use casual words such as "please give us a mike". Use formal and polite language throughout.

• Forgetting the signature: Always end with your name, class, section, and roll number, and add "on behalf of the students of Class..." below your name.

What is the difference between a sound system application and a multimedia classroom application?

A sound system application asks only for audio equipment: a microphone, an amplifier, and speakers, so that every student can hear the teacher. A multimedia classroom application asks for a full set of digital equipment, including a projector, a computer, and a screen, so that lessons can be shown with pictures and videos. A sound system is cheaper and simpler, while a multimedia classroom is more complete but more expensive.
