1 Hour (Approximately)
- THE MISSION
The player works at a construction company along with 10 more of his friends. The work consists of using bulldozer, stone cutting and welding that produces a lot of sound generally and protective gear has to be worn to protect themselves from the noise. Unfortunately, there is a theft that has happened at the company and all the protective gear has been stolen and has been kept at different places across the city as they are valuable and would fetch the thieves a great deal of money. Unaware, your friends go to the construction company and are about to start the work. This will lead to severe damage as they don’t understand the importance of the gear. The gear has been hidden in a 7 vaults at 7 different locations. The vault can only be opened once answered a riddle around prevention of noise pollution. The player has to strategically find the 7 locations in which the gear has been hid and come back on time to provide the gear to the workers before they start working on the equipment. If failed to come back on time, it may lead to severe hearing impairment or can cause life threat. It is a time scoring game and bonus points are provided for every riddle solved.
Noise is the unpleasant and undesirable sound which leads to discomfort to human beings. The intensity of sound is measured in decibels (dB). The faintest sound which can be heard by the Human ear is 1 Db. Due to increasing noise around the civilizations; noise pollution has become a matter of concern. Some of its major causes are vehicles, aircraft, industrial machines, loudspeakers, crackers, etc. Some other appliances also contribute to noise pollution like television, transistor, radio, etc. when used at high volume.
- Types of noise pollution
There are 3 types of noise pollution:
- Transport noise: It mainly consists of traffic noise which has increased in recent years with the increase in the number of vehicles. The increase in noise pollution leads to deafening of older people, headache, hypertension, etc.
- Neighbourhood noise: The noise from gadgets, household utensils etc. Some of the main sources are musical instruments, transistors, loudspeakers etc.
- Industrial noise: It is the high-intensity sound which is caused by heavy industrial machines. According to many researches, industrial noise pollution damages the hearing ability to around 20%.
- Causes and sources of noise pollution
There are several causes of noise pollution:
- Industrialisation: Industrialisation has led to an increase in noise pollution as the use of heavy machinery such as generators, mills, huge exhaust fans are used, resulting in the production of unwanted noise.
- Vehicles: Increased number of vehicles on the roads are the second reason for noise pollution.
- Events: Weddings, public gatherings involve loudspeakers to play music resulting in the production of unwanted noise in the neighbourhood.
- Construction sites: Mining, construction of buildings, etc add to the noise pollution.
Some of the examples of noise pollution are:
- Following are the examples of noise pollution:
- Unnecessary usage of horns
- Using loudspeakers either for religious functions or for political purposes
- Unnecessary usage of fireworks
- Industrial noise
- Construction noise
- Noise from transportation such as railway and aircraft
- Effects of noise pollution on human health
Noise pollution can be hazardous to human health in the following ways:
- Hypertension: It is a direct result of noise pollution which is caused due to elevated blood levels for a longer duration.
- Hearing loss: Constant exposure of human ears to loud noise that are beyond the range of sound that human ears can withstand damages the eardrums resulting in loss of hearing.
- Sleeping disorders: Lack of sleep might result in fatigue and low energy level throughout the day affecting everyday activities. Noise pollution hampers the sleep cycles leading to irritation and uncomfortable state of mind.
- Cardiovascular issues: Heart-related problems such as blood pressure level, stress, and cardiovascular diseases might come up in a normal person and a person suffering from any of these diseases might feel the sudden shoot up in the level.
- Prevention of noise pollution
Some noise pollution preventive measures are provided in the points below:
- Honking in public places like teaching institutes, hospitals, etc. should be banned
- In commercial, hospital, and industrial buildings, adequate soundproof systems should be installed
- Musical instruments sound should be controlled to desirable limits
- Dense tree cover is useful in noise pollution prevention
- Explosives should be not used in forest, mountainous, and mining areas
- Problem statement
The player works at a construction company along with 10 more of his friends. The work consists of using bulldozer, stone cutting and welding that will produce a lot of sound generally and protective gear has to be worn to protect themselves from the noise. There is a theft that happens at the company and all the protective gear has been stolen and has been kept at 7 different places across the city as they are valuable and would fetch the thieves a great deal of money. Also, these gears are kept in a vault and the vault will get opened only if you solve the riddle correctly. Unaware, your friends go to the construction company and are about to start the work. Your task is to find the hidden locations, collect all the gears by opening the vaults and come back on time to the company. On failure, it will lead to severe damage as the friends don’t understand the importance of the gear. It is extremely important to come back on time so as to provide the gear to the workers before they start working on the equipment without which it may lead to severe hearing impairment or even can cause death.
- Game design overview
In the Game, the player is a construction worker and supervisor. Imagine 10 of your friends work alongside you in the construction company and the work consists of using bulldozer, stone cutting and welding that produces a lot of sound. As a preventive measure, the protective gear has to be worn to protect themselves from the noise. But unfortunately, there is a theft that happens at the company and all the protective gear has been stolen and has been kept in a vault at 7 different places across the city as they are valuable and would fetch the thieves a great deal of money. Unaware, your friends go to the construction company and are about to start the work. They are about to start this work in 30 minutes (~10 minutes’ game play). They are unaware of the fact that not wearing gears will lead them to severe damage as they don’t understand the importance of the gear. The player has to strategically find the 7 locations in time and open each vault by solving a riddle. The riddle is not easy to solve and it is around prevention of noise pollution. As a player, you have to solve these riddles, unlock the vault, find the locations and bring back all the gears to the construction company to provide the gear to the workers before they start working on the equipment. On failure, it may lead to severe hearing impairment or even cause life threat to the friends. Finish the game as early as possible to achieve more score and also achieve bonus points on solving each riddle.
- How to design the game?
- Step I
As the game begins, it starts with a background story so as to give a quick brief understanding of the game. Once clicked on continue, you see a timer with 10 minutes’ and reducing continuously. The vaults are randomly present in the city at 7 different locations. You have to strategically think (think for a place possible for the thief to hide such things). The thief can hide it anywhere but his favourite places are park, railway station and bike repair shop. Reach the location find the vault.
Hint: There will be a time counter that will constantly calculate your time remaining to finish. Each time the game begins, the vault location should change randomly to increase the difficulty of the game. You can imagine the city and the places as you need. But the player always starts the game from one location only i.e. the construction site and this is where you have to come back. For help, you can show a map for direction but should not show the vault location.
- Step II
Once you find the vault, the riddle will be shown on the screen asking question related to prevention of noise pollution. Remember to increase the difficulty level of the riddle from one vault to another or one location to another. The player can find any vault and try solving the riddle asked within the time limit. Please note that all the vaults to be found and unlocked to complete the game. If failed, the score achieved will not be called as game score and to be considered as individual score. The game score is to considered only if all the vaults are opened within the game time.
Hint: Prepare the riddle around prevention of noise pollution first and then map them to the particular vault. Make sure that the vaults are not easy to find and riddles not easier to solve. The game will be counted complete only if you open all the vaults, collect all the gears and come back to the base location.
- Step III
This is a time score gaming. Each second correspond to 1 point. Less the time consumed to finish the game, more the score. The score is calculated on the time remaining at the end of the game. For eg. If you have finished the game in 4 minutes which makes it 240 seconds, your game score will be 600 – 240 = 360 points. It is calculated as total game time minus the time taken to complete the game. Along with that, with each riddle solved, you will get 20 points. For eg. On solving all riddles, 7 X 20 points = 140 points. This 140 points gets added to 360 points to make it the game score for the player.
Hint: Target to find the vault location, solve the riddles as early as possible to achieve highest score. The game will always run for 10 minutes so as to see whether the player has completed the task or failed to complete the task. At the end, the score will be calculated. The total combined score of will be the remaining time in seconds and number of riddles solved. This will provide the highest competitive score.
